ConvertAPI

Add ConvertAPI to your product for your customers, and give your AI agents governed access to it.

Embed a ConvertAPI integration so your product can convert your customers' documents and files between formats without you running conversion infrastructure. Each customer's credentials are held and scoped per tenant, so usage is attributable and one customer's conversions never draw on another's allowance. fastn handles the authentication and API upkeep, so a change on the ConvertAPI side lands in the connector rather than your backlog.

In your product

Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.

Let customers convert their own uploads to PDF or another format from inside your product.

Generate a PDF of a document or report your product produces, without bundling a converter.

Convert an incoming file to a format your downstream processing can read before storing it.

Run conversions per tenant so usage and limits stay attributable to the customer who caused them.

For your AI agents

Governed, audited access for the agents you build, through the MCP server.

An agent converts a document to a readable format before summarising it.

An agent produces a PDF of a drafted document within governed permissions.

An agent reacts to a new upload and converts it as the first step of a workflow.

Example prompt

Convert the attached document to PDF and tell me how many pages it produced.

Set up ConvertAPI in 4 steps

  1. 01Open the ConvertAPI connector from your fastn dashboard.
  2. 02Have each customer authenticate their own ConvertAPI account.
  3. 03Map the conversions and formats your product offers, then enable the actions you need.
  4. 04Call them from your product, or expose them to an agent through the MCP server.

Why teams use the ConvertAPI integration

What you get by embedding it with fastn instead of building it yourself.

  • Ship a ConvertAPI integration without building it. Your customers connect their own ConvertAPI account inside your product and work their models, requests and outputs there, with no per-customer code on your side.
  • Handle the part that actually costs time: per-customer keys, quotas and cost attribution matter more than schema here, because every call is billed. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a ConvertAPI update is not your on-call problem.
  • One integration serves your product and your agents. The same governed ConvertAPI connection powers in-product features and gives AI agents scoped, audited access, so you give your product and your agents a model call each customer pays for themselves without wiring it twice.

ConvertAPI integration FAQ

How do I add a ConvertAPI integration to my product?

Enable the ConvertAPI connector in your fastn dashboard, then let each customer authenticate their own ConvertAPI account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no ConvertAPI client code in your app and no per-customer branch in your codebase. Setup is 4 steps.

Do my customers each connect their own ConvertAPI account?

Yes. Every connection is scoped to the individual customer, so each authorises their own ConvertAPI account and only ever sees their own models, requests and outputs. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.

Can AI agents use this ConvertAPI integration?

Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent converts a document to a readable format before summarising it.

Who maintains the ConvertAPI integration?

fastn does. When ConvertAPI changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.

Whose ConvertAPI API key and quota does each call use?

Each customer authorises their own ConvertAPI account, so usage, rate limits and cost land on the customer that caused them. You are not metering a shared key and re-billing it, and one heavy customer cannot exhaust another's quota.

Are inputs and outputs auditable?

Yes. Every call is logged per tenant with the call, the input and the result, so an output can be traced back to what produced it. That matters more here than in most integrations, because a generated answer or an extracted field cannot be reconstructed from the request alone.

What can I build with the ConvertAPI integration?

A common starting point: convert their own uploads to PDF or another format from inside your product. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.

How much does the ConvertAPI integration cost?

It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding ConvertAPI does not change your per-connector cost. You can start free with 3 connected accounts.
