Permissions

• User must have AI_DEVELOPMENT + MANAGE permission in the project

Notes and Warnings

• Blank Secret Preserves Value (INV-06):
  • Sending an empty apiKey / apiSecret / serviceAccountJson keeps the previously stored encrypted value
  • Send a new non-blank value to rotate the secret
• Provider Must Exist:
  • PUT fails with "was not found" if the named provider does not exist — use Create LLM Provider (upsert) to create
• Polymorphic Discriminator:
  • "_class": "llm" is mandatory in the body
• Enum Serialization:
  • Enum values must be sent as the enum constant name (e.g. DEEPSEEK, BEARER, CLOUD, TEXT), not lowercase
• Deploy on Save:
  • The updated provider is re-encrypted and pushed to the AI Gateway workers
