[LiamP]

Is it possible to get an example of this through the integration endpoint before release?

We are contacting you to regarding an Exchange Stream API release scheduled to take place on Tuesday 19th Nov.

Please be aware that, following this release, it will be possible for a Change Message with ChangeType ('ct') SUB_IMAGE to be published while a subscription is on-going.

This message should be interpreted in the same way as the initial image returned at the start of subscription: it contains the current state of all markets matching the existing subscription and should replace any existing values in any local cache.

This may cause a slight pause in message delivery but should be an infrequent event with gaps of weeks to months between occurrences. This will only occur if for some reason the set of markets available to you has changed e.g. due to technical maintenance or licensing changes.

To allow customers to test the above SUB_IMAGE change, we’ll simulate this behaviour on the following dates on the Exchange Stream API integration endpoint - stream-api-integration.betfair.com

Monday - 11th Nov - 10:00 GMT
Tuesday - 12th Nov - 10:00 GMT
Wednesday - 13th Nov - 10:00 GMT
Thursday - 14th Nov - 10:00 GMT
Friday - 15th Nov - 10:00 GMT

At this time, all connections to the stream-api-integration.betfair.com endpoint with receive a Change Message with ChangeType ('ct') SUB_IMAGE
