Connect your own software to your business: make an API key, make your first call, and look up every operation an API key can call.

Get started

Quickstart: Make an API key, see what it can call, and make your first call to the GrowLocal API: listing your business's tables.
Make an API key: An API key lets your own software, such as a script or an app you've built, reach one business through the GrowLocal API.

Authentication: Every request to the GrowLocal API carries an API key in its Authorization header and goes to the address of the business the key was made in.
Make a call and read the receipt: Every operation is called the same way: POST /invocations with what to call, an id you choose and the operation's input.
Retries without doing it twice: A change that fails in transit can be sent again safely: GrowLocal recognises the request by its operationId and answers with the receipt it already has instead of making the change a second time.
Pagination: Long answers come a page at a time with a cursor for the next page: the catalogue, and the rows of a table.
Errors: The API says what went wrong in two ways.
Limits: How much one API key can do at once, and how big a request and its pages can be.
