Create, import, enrol, suppress and delete, plus the lead link forms post to. When a sub-account keeps its contacts here rather than in a CRM, this is the system of record for them. Concepts, and the four ways a contact gets in, are in [Contacts without a CRM](/contacts/native-contacts). Every operation takes `locationId` as a query parameter, and it is the only thing that identifies the tenant. A sub-account with a CRM connected answers `400`: its contacts live in that CRM. ## Contacts | Endpoint | Use it to | | ------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------- | | [List native contacts](/api-reference/native-contacts/list-native-contacts) | Page through contacts, searching a name, an email or part of a number. | | [Create a native contact](/api-reference/native-contacts/create-a-native-contact) | Add one person. `phone` is the only required field. | | [Get a native contact](/api-reference/native-contacts/get-a-native-contact) | One contact, with its custom fields and do-not-call state. | | [Update a native contact](/api-reference/native-contacts/update-a-native-contact) | Change the fields you name, and nothing else. | | [Delete a native contact](/api-reference/native-contacts/delete-a-native-contact) | Cancel their bookings and remove them. | | [Preview a native contact delete](/api-reference/native-contacts/preview-a-native-contact-delete) | What the delete would cancel, before anyone agrees to it. | | [Delete several native contacts](/api-reference/native-contacts/delete-several-native-contacts) | Up to 100 at a time, partial on purpose. | ## Who not to call, and what to remember | Endpoint | Use it to | | --------------------------------------------------------------------------------------------------- | ------------------------------------------ | | [Set native contact do-not-call](/api-reference/native-contacts/set-native-contact-do-not-call) | Stop dialling this person, or start again. | | [Cancel a native contact callback](/api-reference/native-contacts/cancel-a-native-contact-callback) | Drop the callback they have waiting. | | [Add a native contact note](/api-reference/native-contacts/add-a-native-contact-note) | Leave a note for people, on the timeline. | | [Add to contact memory](/api-reference/native-contacts/add-to-contact-memory) | Write what the next call should know. | | [Update a contact memory entry](/api-reference/native-contacts/update-a-contact-memory-entry) | Rewrite one entry. | | [Delete a contact memory entry](/api-reference/native-contacts/delete-a-contact-memory-entry) | Remove one entry, leaving the rest. | ## Custom fields | Endpoint | Use it to | | ----------------------------------------------------------------------------- | -------------------------------------------------------------------- | | [List custom fields](/api-reference/native-contacts/list-custom-fields) | The fields this sub-account defines, and the keys your prompts read. | | [Create a custom field](/api-reference/native-contacts/create-a-custom-field) | Define one.
