      x-ai-description: Performs a bulk upsert of attribute values for a single contact in one atomic request. In SendPulse CRM, contact attributes drive segmentation, personalization, and automation triggers — this endpoint is the preferred way to hydrate a contact's profile after creation or synchronization from an external system, avoiding N separate API calls.
      x-ai-reasoning-instructions:
      - Verify that the contact with the given contactId exists before calling; a 404 here means the contact was deleted or the ID is wrong.
      - Collect all attribute values that need updating and send them in one batch rather than looping with individual calls — this reduces rate-limit exposure and latency.
      - Confirm that each attributeId belongs to the account's attribute schema; submitting an unknown ID will silently fail or error depending on API version.
      - If the same attributeId appears more than once in the array, clarify with the user which value should win — duplicates cause unpredictable behavior.
      - For sensitive attribute types (e.g., phone, email, financial data), check whether the value format matches the attribute's expected type before submitting.
      x-ai-responding-instructions:
      - Confirm which attributes were successfully stored by echoing back the attributeId/value pairs from the 201 response.
      - If the operation was part of a contact import or sync flow, suggest verifying the full contact profile with a GET /contacts/{contactId} call.
      - 'If an error occurs, distinguish between a missing contact (fix: check the ID), unknown attribute IDs (fix: list available attributes first), and validation errors (fix: check value format).'
      x-ai-suggestions:
      - After storing attributes, trigger segmentation refresh or re-evaluate automation conditions that depend on these attributes.
      - Use GET /contacts/attributes to retrieve the full list of available attributeIds for this account before constructing the batch payload.
