API & Integration Prompts for Lovable AI
Adding an API to a Lovable app fails in a predictable place. The request works, the happy path renders, and then the key is in the client bundle, the rate limit is undiscovered, and there is no behaviour for the case where the third party is down. Lovable will not add any of that unless the prompt does.
These sixteen prompts split into two jobs. Roughly half are AI integrations, where the work is prompt design and cost control. The rest are conventional third-party integrations, where the work is auth, retries and reconciliation.

API Request Explorer
What this prompt is for
An in-app API request explorer: compose requests against your API with saved auth, inspect responses with timing, and save named examples the whole team can rerun.
When to use it
When 'try the API' means copying curl from docs into a terminal. Wrong as a general HTTP client; this is your API's guided cockpit.
# Context Build a request explorer for your own API: users compose requests from your actual endpoint catalog, send them with their own credentials, inspect responses, and save named examples for reuse. ## Core Features (Priority Order) 1. Endpoint picker from your API catalog: method, path, described parameters 2. Request composer: path params, query params, headers, JSON body with validation ag

API-Driven Weather Dashboard
What this prompt is for
A weather dashboard built properly against a third-party API: cached responses, explicit refresh, request budget tracking, and graceful degradation when the provider stumbles.
When to use it
As the reference pattern for any external-API dashboard: the weather is the example, the caching and budget discipline are the lesson.
# Context Build a weather dashboard consuming a third-party weather API: current conditions and forecast for saved locations, with response caching, a visible data age, request budget tracking and honest failure states. ## Core Features (Priority Order) 1. Saved locations: add by search, reorder, remove, with current conditions per card 2. Detail view: hourly next 24h, daily next 7 days, sensible

AI PDF Summarizer
What this prompt is for
An AI PDF summarizer with honest limits: upload, extract, summarize with structure, always alongside the source, with page limits, cost caps and extraction-failure truth built in.
When to use it
When users bring documents and want the gist plus the ability to verify it. Wrong for legal-grade extraction; this is orientation, not evidence.
# Context Build an AI PDF summarizer: upload a PDF, extract its text, produce a structured summary shown beside the source, with limits and failures stated plainly and costs controlled per account. ## Core Features (Priority Order) 1. Upload with page and size limits stated up front, progress shown 2. Extraction with per-page status; scanned or image pages reported as unextractable, not silently

AI Analytics Insights
What this prompt is for
An AI layer over your analytics that writes the weekly narrative: what changed, what likely drove it, what to check next, always grounded in the queried numbers it cites.
When to use it
When dashboards exist but nobody reads them, and the question is always 'so what changed?'. Wrong without reliable underlying data; garbage in, confident garbage out.
# Context Build an AI insights layer over an existing analytics dataset: on schedule or on demand, it queries defined metrics, detects changes worth words, and writes a short narrative where every claim cites the number behind it. ## Core Features (Priority Order) 1. Metric bindings: each insight source is a defined query with owner and description, reused from your metrics layer 2. Change detect

AI Multilingual Translator
What this prompt is for
An AI translation tool with production honesty: language pairs, tone control, glossary enforcement for your product's terms, and confidence flags where the model is guessing.
When to use it
When your product or content needs recurring translation with consistent terminology. Wrong for certified legal translation; this is operational translation with memory.
# Context Build a translation tool on an AI model: text in, translation out across your supported language pairs, with a glossary that locks your product terms, tone presets, and honest handling of ambiguity. ## Core Features (Priority Order) 1. Translate: source text, target language, output beside input with copy 2. Glossary: your terms with required translations per language, injected into eve

AI Chat Assistant Integration
What this prompt is for
An in-product AI chat assistant with boundaries: answers grounded in your docs and the user's context, honest refusals, conversation memory that respects cost, and escalation to humans.
When to use it
When support volume is repetitive and your docs already hold the answers. Wrong without a docs corpus worth grounding in; write the docs first.
# Context Build an in-product chat assistant: users ask questions, answers ground in your documentation and their account context, sources are cited, unanswerable questions escalate to a human channel gracefully. ## Core Features (Priority Order) 1. Chat UI: streaming responses, message history within the conversation, typing and error states 2. Grounding: retrieval over your docs corpus; answers

API Auto-Documentation Generator
What this prompt is for
Documentation generated from your API's actual spec: endpoints, schemas and examples rendered as fast indexable pages that cannot drift from the implementation they describe.
When to use it
When your API docs are a manually edited page that lies a little more each release. Wrong without a machine-readable spec; write the OpenAPI file first, then generate.
# Context Build an API documentation generator: parse the OpenAPI spec, render per-endpoint pages with parameters, schemas, responses and runnable examples, rebuilt on spec change so drift is impossible. ## Core Features (Priority Order) 1. Spec parsing: endpoints, parameters, request/response schemas, auth requirements, with a validation report of spec gaps 2. Per-endpoint pages: description, pa

AI Image Captioner
What this prompt is for
An AI image captioner producing accessibility-grade alt text and searchable descriptions: batch processing, length and style rules, confidence flags, and human review where it matters.
When to use it
When an image library needs alt text at scale, for accessibility compliance or searchability. Wrong for medical or safety-critical description; human eyes own those.
# Context Build an image captioning tool: upload images singly or in batch, generate alt text and longer descriptions to defined style rules, flag low-confidence results for review, and export in useful formats. ## Core Features (Priority Order) 1. Upload: single and batch with per-image progress and format validation 2. Two outputs per image: alt text (under 125 characters, subject-first) and a

AI Driven Research Assistant
What this prompt is for
A research assistant that keeps receipts: questions answered from gathered sources with per-claim citations, a source panel with quotes, and a stated boundary between found and inferred.
When to use it
For recurring research workflows where traceability matters: market scans, competitor watch, literature orientation. Wrong when the answer must be authoritative; this maps the terrain.
# Context Build a research assistant: a question spawns a research run that gathers from configured sources, extracts relevant passages, and composes an answer where every claim links to its supporting quote. ## Core Features (Priority Order) 1. Research runs: question in, status through gathering, extraction and composition, answer out 2. Source panel: every document consulted, with the exact pa

Simple Social Login Connector
What this prompt is for
Social login done to production standard: two providers, account linking by verified email, a fallback path, and the edge cases (revoked access, changed email) handled before they page you.
When to use it
When signup friction measurably costs you users and your audience lives on Google or GitHub. Wrong as the only auth path; email fallback is non-negotiable.
# Context Add social login to an app: two OAuth providers with correct flows, account creation and linking rules by verified email, coexisting with email/password, with every edge case given a decided behavior. ## Core Features (Priority Order) 1. Sign in with Google and one more provider fitting your audience, standard OAuth authorization-code flow 2. Account rules: new social sign-in with an em

Public API Explorer
What this prompt is for
A public API catalog and console: browsable categorized APIs with capsule documentation and a try-it console, server-rendered so every API page earns search traffic.
When to use it
For building a developer-facing directory product, or the discovery layer over your own multiple APIs. The pattern is catalog plus console plus indexable pages.
# Context Build a public API explorer: a catalog of APIs with structured capsule pages (what it does, auth model, rate limits, example call) and an in-browser console to try requests, all server-rendered. ## Core Features (Priority Order) 1. Catalog: APIs with category, auth type, pricing model, capsule description, searchable and filterable 2. API detail pages: overview, auth requirements, key e

AI Action History Logger
What this prompt is for
An audit log for AI actions in your product: every generation recorded with inputs, outputs, model, cost and actor, queryable enough to answer 'why did it say that' months later.
When to use it
The moment AI output ships to users: support, compliance and debugging all eventually ask what the model was given and what it returned. Wrong to retrofit; log from the first call.
# Context Build an AI action logger: every model call in your product writes a structured record (actor, feature, prompt inputs, output, model, tokens, cost, latency), with a browse-and-search UI and retention rules. ## Core Features (Priority Order) 1. The log write: one function wrapping every model call, recording before and after, failing open so logging never blocks the feature 2. Browse UI:

AI Text Classification API Integration
What this prompt is for
Text classification through an AI API with production discipline: a versioned label set, confidence thresholds with a review queue, batch processing, and drift monitoring.
When to use it
When incoming text needs routing at volume: tickets, leads, feedback, content. Wrong when a keyword rule solves it; try the dumb version first, classify when it breaks.
# Context Build a text classification service on an AI API: input text is labeled against your defined label set with confidence, low-confidence items queue for human review, and everything is measured against drift. ## Core Features (Priority Order) 1. The label set: names, definitions and two examples each, versioned as data, injected into every classification request 2. Classify endpoint: text

Payment Provider Webhook Integration
What this prompt is for
Payment provider webhooks as the source of truth: verified, idempotent event processing that drives entitlements, with reconciliation against the provider and a paper trail for every money event.
When to use it
The moment payments exist: checkout success pages lie, webhooks are the truth. Wrong to treat as optional; unprocessed payment events are revenue leaks with a timestamp.
# Context Integrate payment provider webhooks: signature-verified events drive subscription and entitlement state, processing is idempotent and ordered, failures alert loudly, and a reconciliation view proves your database agrees with the provider. ## Core Features (Priority Order) 1. Verified receipt: signature checked, raw event stored, fast acknowledgment, processing async 2. The event handler

Third-Party CRM Sync Integration
What this prompt is for
A two-way CRM sync with declared rules: field mapping, sync direction and conflict policy stated per field, a sync log that explains every change, and drift detection between systems.
When to use it
When your product's account data and the CRM diverge and both teams think theirs is right. Wrong without deciding field ownership first; sync automates your decisions, it cannot make them.
# Context Build a CRM sync: your product's accounts and contacts against the CRM's, with per-field mapping, direction and conflict rules declared as configuration, changes logged with reasons, and drift surfaced. ## Core Features (Priority Order) 1. Field mapping config: your field, their field, direction (push, pull, two-way), conflict winner, transform if any 2. Sync engine: scheduled and on-de

Feature Flag Service Integration
What this prompt is for
Integrating a hosted feature-flag service properly: one evaluation wrapper, typed flag definitions, local fallbacks for provider outages, and flag lifecycle hygiene from day one.
When to use it
When you choose a flag provider over building your own: the integration discipline decides whether flags stay an asset. Wrong to sprinkle provider SDK calls through the codebase.
# Context Integrate a hosted feature-flag service: all evaluation flows through one wrapper with typed flag definitions, defaults that work offline, environment separation, and a registry that keeps flags from becoming permanent. ## Core Features (Priority Order) 1. The wrapper: one module owning the provider SDK; the rest of the codebase imports flags, never the provider 2. Typed flag registry:

Get the 101-Prompt BundleWhich growth channels these prompts serve
Every prompt in this category carries a distribution section naming the channel it is built for, so the generated app has a way of being found rather than only a feature set. Here is how this category's prompts distribute across channels, counting both primary and secondary coverage.
- Product-led Growth (12 prompts)
- Create a product experience where users reach a meaningful 'aha moment' before they ever have to sign up, pay, or talk to sales.
- Organic SEO / AI Search (8 prompts)
- Design your product so it naturally attracts traffic by creating pages that directly answer what users are already searching for and get picked up by Google and AI search engines.
- B2B Sales / Outreach / LinkedIn (6 prompts)
- Get a product structure that can be explained in one message and clearly ties features to business outcomes decision-makers care about.
- Email Marketing (5 prompts)
- Build a reason for the product to send something a user actually wants to open, so the list becomes a retention channel rather than a broadcast list.
- Community-led Growth (3 prompts)
- Design your product so users benefit from contributing, sharing, or improving it together, causing value to compound over time.
Which integration prompt to use
For AI features, start from the output shape. AI Text Classification API Integration and AI Analytics Insights return structured data you can act on. AI Chat Assistant Integration and AI Driven Research Assistant are conversational. AI PDF Summarizer and AI Image Captioner take a file and return text. The interface differs far more than the model call does.
For conventional integrations, Payment Provider Webhook Integration and Third-Party CRM Sync Integration are the two where getting it wrong costs money or data. Social Login Connector and Feature Flag Service Integration are lower-stakes places to start.
API Request Explorer and API Auto-Documentation Generator are for understanding an API before you commit to it, which is usually worth one prompt of its own.
Suggested build order
Understand the API, then call it safely, then handle it failing.
Explore before you integrate
One prompt to see the actual response shape beats guessing at it in application code.
Prompt: API Request Explorer
Start with a low-stakes integration
Get the server-side key handling pattern right where a mistake is cheap.
Prompt: Simple Social Login Connector
Then the ones that matter
Webhooks with signature verification, idempotency and replay handling specified.
Prompt: Payment Provider Webhook Integration
Make failures visible
In Backend Logic, and the piece most often missing when an integration silently stops.
Prompt: API Error Tracker
Where integration prompts usually go wrong
- Letting the key reach the browser. State that the call is server-side and that the key comes from an environment variable. Lovable will otherwise produce a working client-side fetch with the secret in it.
- No idempotency on webhooks. Providers retry. Code that assumes one delivery per event will double-charge, double-create or double-email, and it will look correct in testing.
- Treating an AI call as deterministic. Specify what happens when the model returns something unparseable, because it will, and an unhandled parse failure surfaces as a blank screen.
- Ignoring cost until it is a bill. For anything AI-shaped, prompt for a usage limit at the same time as the feature.
Frequently asked
How do I add an API to a Lovable app?↓
Call it from a server function rather than the browser, with the key in an environment variable, and specify both in the prompt. Then handle the three cases Lovable omits: the request failing, the response being unparseable, and the provider rate-limiting you. Every prompt in this category names those explicitly, because a generated integration that only covers the happy path is the default outcome.
Can Lovable connect to any third-party API?↓
Anything reachable over HTTP with a documented auth scheme. The practical limit is not the API, it is whether the prompt says enough about failure handling and key storage for the result to be safe to deploy.
Which AI model do the AI prompts assume?↓
They are written to be model-agnostic and specify the call shape and the output contract rather than a provider, so the same prompt works whichever provider you wire up.
Where do webhooks belong, here or in Backend Logic?↓
Receiving and verifying a webhook is an integration and lives here. Processing the event, retrying and recovering from a bad batch is backend logic. The two prompts are designed to be used together.
