The Paymo API allows developers to access all the data in a Paymo account programatically. This can be used for third party integrations with our app, on-site backup processes or data extraction. The Paymo API is a RESTful API that uses XML/JSON for serialisation. The accepted request types (HTTP verbs) are: GET, POST, PUT, DELETE.
When using the Paymo API with third-party software, we recommend that you use API Keys instead of asking for the user’s email and password.
