How to delete customers
Learn how to delete customer data from DoubleTick — one contact at a time, in bulk, for a filtered segment, or your entire account — plus how to do it through the public API.
Managing customer data responsibly matters for every business. DoubleTick's Delete Customer Data feature lets you remove customer information in a secure, controlled way — from inside the app or through the public API.
What's covered
Who can delete customer data?
Not everyone on your team can delete customer data — it depends on the role and permissions assigned to them.
The account owner has full access and can delete customers, including all data.
Users with owner-level access can also perform deletion actions.
If you've created custom roles, only users explicitly given the Delete Customer permission can delete data — see How to set permissions for custom organization role to configure this.
Team members without this permission won't see or be able to use the delete option at all.
Which customers do you want to delete?
Before you start, it helps to be clear on scope — do you want to delete all your customers, or only the customers in a particular segment or broadcast list? If it's a specific segment, go to the Customers tab and open that segment — it'll be named after the broadcast list it belongs to. From there:
Click the checkbox to the left of the Name column header to select all customers in that segment, or
Manually select only the specific customers you want to remove.
Once you've made your selection, click Delete. If you haven't set up segments yet, see how to create customer segments first.
Ways to delete customers
DoubleTick gives you five ways to delete customer data, depending on what you need:
Individual contact deletion: Use this when you want to delete a single customer. Go to the Customers tab and search for the contact you want to delete. Select the contact and click Delete to remove it.
Deleting customers from a segment or broadcast list: If you want to delete customers from a specific segment or broadcast list, open the relevant segment from the Customers tab. Select the customers you want to delete, or click the checkbox on the left side of the list to select all customers in that segment. Then, click Delete.
Delete all customer data: Use this option when you want to permanently delete all customer data from your DoubleTick account. In the Customers tab, click Delete All in the top-right corner. Enter the OTP sent to the account owner's registered phone number to confirm the deletion. Once verified, the deletion will be processed, and you'll receive a confirmation message through email and WhatsApp.
Deleting customers using the public API
You can also delete customers programmatically, without needing internal UI access — useful if you're managing customer data from your own systems.
The endpoint is
DELETE /customer. It accepts aphoneNumbersarray (max 10 per request) and queues them for deletion — it runs through the same underlying deletion pipeline used inside the app, so behaviour stays consistent either way.If any of the numbers you send don't match a customer in your org, the response tells you exactly which ones in
notFoundPhoneNumbers— and if none of them matched at all, you'll get a404.
This endpoint requires the DELETE_CUSTOMER permission on the user the API key is bound to, and is capped at 200 deletes/day and 30 requests/minute per org.
For the full request and response reference, see the Delete Customer API documentation. You'll need an API key to call it — see How to Create and Manage Your API Key in DoubleTick if you don't have one yet.
Important considerations
Permissions for deletion:
Only users with the correct permissions can delete customer data.
The in-app deletion methods require permission from the account owner.
Permissions can be configured under custom roles and responsibilities.
Irrecoverable action:
Once customer data is deleted, it cannot be recovered.
Always double-check before confirming deletion.
Security and compliance:
The Delete All option is protected with OTP verification.
This ensures that only authorized users can perform large-scale deletions.
Key takeaways
You can delete customers one at a time, in bulk, by filtered cohort, entirely, or through the public API.
Decide your scope first — all customers, or just one segment/broadcast list — before you start.
Deleting through the API uses the same pipeline as in-app deletion, so the result is identical either way.
API deletion needs the DELETE_CUSTOMER permission and is limited to 200 deletes/day and 30 requests/minute per org.
Deletion is permanent and cannot be undone — double-check before confirming.
