Hello, can I check if anything has recently changed with the Graph API in terms of authentication ? I ask as the below worked last year (and continues if I attempt the webhook endpoint manually when I do indeed get a 200 OK response back.)
cometd-app_1 | [15:52:14] WARN msGraph/54b6f1bd-db37-4f48-a64c-c14eec2bd681: {
cometd-app_1 | error: {
cometd-app_1 | code: 'InvalidRequest',
cometd-app_1 | message: 'Subscription validation request failed. Notification endpoint must respond with 200 OK to validation request.',
cometd-app_1 | innerError: {
cometd-app_1 | date: '2021-01-07T15:52:14',
cometd-app_1 | 'request-id': '7a468b24-2226-41b3-bc42-df84a0ed2d68',
cometd-app_1 | 'client-request-id': '7a468b24-2226-41b3-bc42-df84a0ed2d68'
cometd-app_1 | }
cometd-app_1 | }
cometd-app_1 | }
Is there any form of service status indicator for the Graph API ?
thanks
