Called once per opened conversation; providers that fail or time out are reported in `sources` without failing the request. ## OpenAPI ````yaml /api/services-api.yaml get /v1/tenants/{tenantID}/sessions/{sessionID}/processing-traces openapi: 3.0.3 info: description: >- Talqui is an omnichannel customer service platform that unifies conversations from WhatsApp, Instagram, Telegram, and many other channels into a single attendant panel, alongside a broader ecosystem of plugins and integrations. This API gives developers programmatic access to Talqui's services layer, exposing the operations needed to read and manage tenants, conversations, plugins, and related resources that power that platform. Authentication is available on behalf of an Operator (the default for this API), a Plugin Connection, or a Plugin — see the [Talqui authentication guide](https://docs.talqui.chat/guides/introduction/authentication/) for how each token is obtained and when to use it.
