Response status by service

BulkSMS JSON API PHP webhook

Response status
Not listed
Response information checked
2026-10-27 Rechecked: 2026-10-27

The PHP webhook sample reads a JSON array and distinguishes RECEIVED/SENT. Incoming messages and status reports require two trigger scopes; handle empty-array tests, respond within 30 seconds and account for duplicate updates.

Scope: Only customer-side PHP integration was verified. The provider platform’s PHP2Shell response, impact and remediation are unconfirmed.

What users should do

Check the PHP client and runtime, and test installation and authentication in a sandbox. Ask the runtime administrator about PHP updates.
