Head over to the API Reference and look for "Launch a Workflow".
API Playground
We've built the API playground to facilitate API integration: we strongly encourage you to use it.
Integration Accounts
Using version 3 of the API, you can use accounts you previously synchronized in the Integrations section.
To get one's account UID, go to the integration of your choice and click on copy UID on the account:
Once you have this UID, you can use it to schedule a workflow with the account, using the following in the payload (refer to the API Reference for the full payload):
"accounts": {"UID_YOU_JUST_GOT": {}}
If you need to update a cookie, for example with LinkedIn, use the following:
"accounts": {"UID_YOU_JUST_GOT": {"cookies": {"li_at": "YOUR_NEW_VALUE"}}}
