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.

    The “Try in Lovable” links on this page are affiliate links: we may earn a commission if you create an account through one. It costs you nothing and does not change which prompts are here.

    API & Integration

    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

    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.

    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

    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

    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

    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.

    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.

    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)

    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

    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)

    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

    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)

    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.

    Which 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.

    1. Explore before you integrate

      One prompt to see the actual response shape beats guessing at it in application code.

      Prompt: API Request Explorer

    2. Start with a low-stakes integration

      Get the server-side key handling pattern right where a mistake is cheap.

      Prompt: Simple Social Login Connector

    3. Then the ones that matter

      Webhooks with signature verification, idempotency and replay handling specified.

      Prompt: Payment Provider Webhook Integration

    4. 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.
