Update Campaign

Use this endpoint to update the steps, emails and content of an email sequence.

In the campaign, you must provide a default subject line. If you do provide a new subject line in steps other than the first one, it'll instruct Interseller to send the email in a new thread rather than a reply in the same thread.
It is recommended to use markdown since this is what our editor uses. However, you can also use HTML too.
Wait days is the number of days to wait. If wait days is 2 and the previous email was sent on Monday, the next day it'll send is Thursday since two days have to wait in between.

A/B Testing

To create an A/B test, you can create additional steps by providing a similar step structure in the other_steps array and reference the step ID in the _step parameter of the "B" step you are creating.

You can reference either the index of the step you are trying to create an A/B test for or the ID of that step.
You do not need to include other parameters like wait_days since the main step serves as the primary configuration.
On the right, select the "Adding an A/B test" example to see how to create an A/B test.
