Sequences are outreach campaigns that sales teams use to reach out to contacts over a planned period of time.

Use the Activate a Sequence endpoint to start an inactive sequence. Once activated, the sequence begins sending emails to its contacts on the configured schedule. The sequence must have at least one step configured before it can be activated.

This endpoint requires a master API key. If you call the endpoint without a master key, you receive a 403 response. Check out Create an API Key to learn how to create a master key.
