Autumn connector

Back to the connector overview, authentication methods, and actions.

breakingRemoved the multi-update subscription action. Autumn’s endpoint accepts every request and applies nothing, so the action could only ever report success without cancelling or uncancelling anything — use the single subscription update action instead, once per subscription.

description-fixClarified that plan and feature identifiers must be IDs rather than display names and that a feature’s label should be resolved with a lookup first, documented that recalculating balances on delete also requires a feature ID, mirrored the refund and proration mutual-exclusion rules onto the multi-update preview, noted that tiered credit schemas must be configured in the Autumn dashboard and that a reset interval is ignored on continuous-use features, and distinguished the single-record and list read actions.

guide-changesAdded the Autumn dashboard URL to the API Key connection guide, corrected the Secret Key field description to point to Developer > API Keys and the environment switcher, and removed the external support link so the Connection guide button opens the StackOne guide.

description-fixClarified action descriptions from MCP agent testing. create_schedule now tells callers to reuse a fresh server timestamp (get_or_create_customer’s created_at) for the first phase instead of guessing the current time; credit_schema is required for credit_system and rejected on ai_credit_system; track_token_usage.model_id needs the models.dev provider/model form; proration requires both on_increase and on_decrease; import_billing takes a plan id, not a display name; and a price needs exactly one of amount or tiers.

new-actionsInitial Autumn connector with 64 actions across billing, balances, customers, entities, plans, features, referrals, rewards, licenses, keys, invoices, and events. Live-tested against the Autumn sandbox. Added the API Key connection guide and inbound webhook events (Svix-delivered). Doc-audit fixes — plan_id/new_plan_id/currency constraints and removal of the non-existent create_plan version param, and added track_token_usage timestamp/overage_behavior/async params; exposed optional start_cursor on paginated lists; enforced default_markup min via rules; removed deprecated create_schedule preserve_add_ons param; fixed nested price amount/currency/tier types, batch_track raw-array spread, create_reward duration.length, and documented provider cross-field rules.
