Returns the provider URL to send the customer’s browser to, either to create an integration (name, plus the provider’s connection.fields) or to reconnect one (integration_id). Requires a signed-in browser session, not an API key. Keep browser_nonce in session storage: completion needs it. The attempt expires after ten minutes and nothing is stored until it completes. ## OpenAPI ````yaml /openapi-preview.json post /v1/integrations/authorizations openapi: 3.1.0 info: title: Watchdog API (preview) version: 1.0.0 description: >- Development preview for agreements, price items, document relationships, canonical invoices, alerts and alert topics, claims and attached alerts, shared entity activity and comments, Document uploads, invoice imports, explicit invoice-agreement matching, and workflow runs. This contract is under development and is not served by api.watchdog.no. Request bodies are limited to 2 MiB (2,097,152 bytes), including all JSON fields and line data, except POST /v1/support/contact which permits 32 MiB for base64 attachments. File bytes are uploaded directly to storage. The existing public REST service retains its separate contract. servers: - url: http://localhost:3500 description: Local development Worker security: [] paths: /v1/integrations/authorizations: post: tags: - Integrations summary: Start a provider authorization description: >- For providers whose connection method is provider_authorization.
