Introduces a new Sentry.setConversationId() API to track multi turn AI conversations across API calls.

We want to leverage each AI frameworks built-in functionalities wherever possible. OpenAIs conversation_id, sessions, etc to create the gen_ai.conversation.id attribute.
However if the framework does not provide such a mechanism (such as Google GenAI or Anthropic) we shall provide a common function: Sentry.setConversationId(...) or sentry_sdk.set_conversation_id(), which adds the conversation ID to the Scope in a similar way as Sentry.setUser() and sentry_sdk.set_user() do. When provided in such a way it will override any automatically detected value.

Why not just add this as an attribute?
it should only appear as a span attribute, not propagate to logs and metrics. This keeps AI conversation context isolated to spans where it's semantically relevant.

Thanks for making the changes! LGTM now!

In the future, we also might want to export conversationIdIntegration from SDKs but as long as there's nothing to configure, I think it's fine to leave it unexported. Happy to leave that up to you :)

Integration uses spanStart instead of agreed spanEnd hook

High Severity

The integration uses client.on('spanStart', ...) but the PR discussion explicitly agreed on client.on('spanEnd', ...). With spanStart, the scope's conversation ID is set first, then auto-detected values from OpenAI/LangGraph integrations override it during span execution. The PR description states scope-level values should "override any automatically detected value" which requires spanEnd so the scope value is applied last and takes precedence.

Thanks for making the changes! LGTM now!
In the future, we also might want to export conversationIdIntegration from SDKs but as long as there's nothing to configure, I think it's fine to leave it unexported. Happy to leave that up to you :)

Integration uses spanStart instead of agreed spanEnd hook
High Severity
The integration uses client.on('spanStart', ...) but the PR discussion explicitly agreed on client.on('spanEnd', ...). With spanStart, the scope's conversation ID is set first, then auto-detected values from OpenAI/LangGraph integrations override it during span execution. The PR description states scope-level values should "override any automatically detected value" which requires spanEnd so the scope value is applied last and takes precedence.

Introduces a new Sentry.setConversationId() API to track multi turn AI conversations across API calls.
We want to leverage each AI frameworks built-in functionalities wherever possible. OpenAIs conversation_id, sessions, etc to create the gen_ai.conversation.id attribute.

However if the framework does not provide such a mechanism (such as Google GenAI or Anthropic) we shall provide a common function: Sentry.setConversationId(...) or sentry_sdk.set_conversation_id(), which adds the conversation ID to the Scope in a similar way as Sentry.setUser() and sentry_sdk.set_user() do. When provided in such a way it will override any automatically detected value.
Why not just add this as an attribute?

it should only appear as a span attribute, not propagate to logs and metrics. This keeps AI conversation context isolated to spans where it's semantically relevant.

Thanks for making the changes! LGTM now!
In the future, we also might want to export conversationIdIntegration from SDKs but as long as there's nothing to configure, I think it's fine to leave it unexported. Happy to leave that up to you :)

Introduces a new Sentry.setConversationId() API to track multi turn AI conversations across API calls.
We want to leverage each AI frameworks built-in functionalities wherever possible. OpenAIs conversation_id, sessions, etc to create the gen_ai.conversation.id attribute.

However if the framework does not provide such a mechanism (such as Google GenAI or Anthropic) we shall provide a common function: Sentry.setConversationId(...) or sentry_sdk.set_conversation_id(), which adds the conversation ID to the Scope in a similar way as Sentry.setUser() and sentry_sdk.set_user() do. When provided in such a way it will override any automatically detected value.
Why not just add this as an attribute?

it should only appear as a span attribute, not propagate to logs and metrics. This keeps AI conversation context isolated to spans where it's semantically relevant.

Collaborator
Introduces a new Sentry.setConversationId() API to track multi turn AI conversations across API calls.
We want to leverage each AI frameworks built-in functionalities wherever possible. OpenAIs conversation_id, sessions, etc to create the gen_ai.conversation.id attribute.

However if the framework does not provide such a mechanism (such as Google GenAI or Anthropic) we shall provide a common function: Sentry.setConversationId(...) or sentry_sdk.set_conversation_id(), which adds the conversation ID to the Scope in a similar way as Sentry.setUser() and sentry_sdk.set_user() do. When provided in such a way it will override any automatically detected value.
Why not just add this as an attribute?

it should only appear as a span attribute, not propagate to logs and metrics. This keeps AI conversation context isolated to spans where it's semantically relevant.

Thanks for making the changes! LGTM now!
In the future, we also might want to export conversationIdIntegration from SDKs but as long as there's nothing to configure, I think it's fine to leave it unexported. Happy to leave that up to you :)

Integration uses spanStart instead of agreed spanEnd hook
High Severity
The integration uses client.on('spanStart', ...) but the PR discussion explicitly agreed on client.on('spanEnd', ...). With spanStart, the scope's conversation ID is set first, then auto-detected values from OpenAI/LangGraph integrations override it during span execution. The PR description states scope-level values should "override any automatically detected value" which requires spanEnd so the scope value is applied last and takes precedence.
