Overview

The Remove Contact To Sequence operation in the "Sequence" resource of the WTS Chat n8n node allows you to remove a contact from a specific sequence. This is useful for managing automated messaging or workflow sequences, ensuring that contacts are no longer part of a particular campaign or automation flow.

Common scenarios:

  • Unsubscribing a user from a drip campaign.
  • Stopping further automated messages to a contact who has opted out.
  • Dynamically managing contact participation in marketing or notification sequences.

Practical example:
If a user replies with "STOP" to your campaign, you can use this node to automatically remove them from the ongoing sequence.

Properties

Display Name Type Description
Sequence ID String The unique identifier of the sequence from which the contact will be removed.
Contact ID String The unique identifier of the contact to remove from the sequence.
Phone Number String The phone number of the contact to remove from the sequence.

Note:
You must provide either the Contact ID or the Phone Number. If both are empty, the node will throw an error.

Output

The output is a JSON object reflecting the result of the removal operation. The structure depends on the API response but typically includes:

{
  "success": true,
  "message": "Contact removed from sequence",
  // ...other possible fields depending on API implementation
}
  • If the operation is successful, success will be true.
  • Additional information or error details may be included as provided by the WTS Chat API.

Dependencies

  • External Service: Requires access to the WTS Chat API.
  • API Key: You must configure valid WTS Chat API credentials (wtsApi) in n8n.
  • n8n Configuration: No special environment variables beyond standard credential setup.

Troubleshooting

Common Issues:

  • Missing Contact Information:

    • Error Message: "Remove a contact either by ID or phone number"
    • Resolution: Provide at least one of Contact ID or Phone Number.

  • Invalid or Missing Sequence ID:

    • Error Message: May return an error if Sequence ID is missing or invalid.
    • Resolution: Ensure the Sequence ID field is filled with a valid value.

  • API Authentication Errors:

    • Error Message: Related to invalid or missing API key.
    • Resolution: Check and update your WTS Chat API credentials in n8n.

  • Network/API Errors:

    • Error Message: Various, depending on API/server issues.
    • Resolution: Verify network connectivity and WTS Chat service status.
