The Paymo is a RESTful API that uses JSON/XML for serialization.
Accepted request types (HTTP verbs) are: GET, POST, PUT, DELETE.
Making a request
The API base URL is
https://app.paymoapp.com/api/. It is SSL/TLS 1.2 only. There is no way to use the API over unsecure http:// protocol.
An example request using
curl for retrieving the list of clients may look like this:
curl -u email:password -H 'Accept: application/json' https://app.paymoapp.com/api/clients
Updating a client using
curl may look like:
curl -u email:password -H 'Accept: application/json' -d "name=updated%20name" https://app.paymoapp.com/api/clients/12345
See sample code examples on how to make a request to the API.
Read the authentication guide for more details.
Request and response content types
Paymo API supports JSON as well as XML for data serialization, as well as specific types such as PDF, XLS for reports, invoices, estimates.
Read more about content types.
Response codes and error handling
The Paymo API will return a 2xx status code for successful requests. The 4xx error means an error on the user side. And the 5xx errors are returned when the Paymo service is having trouble processing your request.
The response in case of error will contain an error message to help you fix it.
You may want to consult a reference for HTTP Status codes.
If you exceed the rate limit, you'll get a 429 Too Many Requests response and for all following requests until the limit expires. A header
Retry-After will also be returned and will represent the number of seconds you should wait before making the next request.
The following response headers will help you with the current API usage:
X-Ratelimit-Decay-Period: the length in seconds of the current time interval for which the limits are applied
X-Ratelimit-Limit: the total number of API requests allowed per decay period
X-Ratelimit-Remaining: the number of remaining API requests in the current decay period

Including related content
If you want a response to include additional information about an object, you can do so by supplying the
partial_include parameters in the request URL.

Webhooks allow for 3rd party integrations.
By creating a webhook you create a link between an event in Paymo (e.g. adding a task) and a URL that will be notified by Paymo when the event occurs.
