Delete message history

Removes the messages from the history of a specific channel.

  • If you supply neither a start nor an end parameter, the server deletes all messages for that channel.
  • If you supply a start parameter without an end parameter, the server deletes all messages before that time. Start time is exclusive, meaning that a message with that timestamp will not be deleted.
  • If you supply an end parameter without a start parameter, the server deletes all messages from the current time until the end time. End time is inclusive, meaning that a message with that timestamp will be deleted.
  • If you supply both a start and an end parameter, the server deletes all messages from the start time through the end time. Start time is exclusive, and end time is inclusive.
  • If you supply both a start and an end parameter, and their values are equal, the server deletes no messages.
  • To delete a single message, set the parameter values as follows: end = messageTimetoken and start = messageTimetoken(int) + 1
  • If you have Access Manager enabled for your subkey, the request needs to have a signature or authKey.
Path Parameters
sub_key string — REQUIRED

Your app's subscribe key from Admin Portal.

Example: sub-c-50264475-1902-558x-d213-7p19052012n2

channels string — REQUIRED

The channel names to perform the operation on.

Example: ch1,ch2

Query Parameters
start number

Timetoken delimiting the start of time slice (exclusive) to pull messages from. Exclusive means that the message associated with the timetoken will be excluded from the result.

If provided, lets you select a start date, in Timetoken format. If not provided, it will default to current time. Page through results by providing a start OR end time token. Retrieve a slice of the time line by providing both a start AND end time token. start is exclusive, that is, the first item returned will be the one immediately after the start Timetoken value.

Example: 123323123123123

end number

Timetoken delimiting the end of time slice (inclusive) to pull messages from. Inclusive means that the message associated with the timetoken will be included in the result.

If provided, lets you select an end date, in Timetoken format. Page through results by providing a start OR end time token. Retrieve a slice of the time line by providing both a start AND end time token. End is inclusive, that is, if a message is associated exactly with the end Timetoken, it will be included in the result.

Example: 123323123123123

auth string

String which is either the auth key (PAM v2) or a valid token (Access Manager) used to authorize the operation if access control is enabled.

Example: authKey / p0thisAkFl043rhDdHRsCkNyZXisRBjoERtZXRhoENzaWdYIGOAeTyWGJI

uuid string

A UTF-8 encoded string of up to 92 characters used to identify the client.

Example: myUniqueUserId

signature string

Signature used to verify that the request was signed with the secret key associated with the subscriber key.

If Access Manager is enabled, either a valid authorization token or a signature are required.

See Access Manager documentation for details on how to compute the signature.

timestamp integer

Unix epoch timestamp used as a nonce for signature computation. Must have no more than ± 60 second offset from NTP.

Required if signature parameter is supplied.
