newrelic_accept_distributed_trace_payload_httpsafe (PHP agent API)

Syntax

newrelic_accept_distributed_trace_payload_httpsafe(string $httpsafe_payload, string $transport_type)

Accepts a distributed trace payload that includes an HTTPSafe (Base64 encoded) JSON string.

Requirements

Requires PHP agent version 8.4 or higher.

Description

Distributed tracing allows you to see the path that a request takes as it travels through a distributed system. This is useful, for example, when individual transactions occur in multiple services, and you want to examine them as a complete transaction trace.

Important

With PHP agent version 9.10 or higher, the following JSON functions are now considered deprecated and will be removed in a future release:

newrelic_create_distributed_trace_payload()newrelic_accept_distributed_trace_payload($payload)newrelic_accept_distributed_trace_payload_httpsafe($payload)

Instead, use the API that is compatible with W3C Trace Context support, added in agent version 9.8. With this, the API for manually instrumenting applications has changed from the JSON payload related functions to the following header array forms:

newrelic_insert_distributed_trace_headers($outbound_headers)newrelic_accept_distributed_trace_headers($inbound_headers)
