What is the External Integration API?
The External Integration API is used to let your publishers pull offers into their system. It provides an API URL and an API token which acts like a password to pull the data.
Where to find it:
Go inside the publisher tab and select the specific publisher. Under tab "Publisher Access" below you'll find the section "External Integration API". By turning on the switch on the right, the "Generate API Token" will be enabled.
Once you click on it, an unique API URL and API Token will be generated, which your publisher can use/give in order to the integration process.
