Take the `adapterId` and `credentialKey` from `getPartnerAdapterConnections`. Saving a key that is already connected replaces it. **What Widgetic does with it.** The key is stored encrypted, bound to this partner, this adapter and this credential, so that a stored value cannot be moved to another. It is never returned, never logged and never shown to a visitor of a widget or to your customers. A server of Widgetic opens it for the one call a widget makes through the adapter, uses it to call the provider on the partner's behalf, and discards it. To cut that off, remove the key here, or revoke it with the provider. **What is checked.** That the adapter exists and takes this credential, that a partner may keep it (some are for an owner only) and that the text is one line of at most 2048 characters. Whether the provider accepts the key is not checked here: it shows the first time a widget uses it. **An address that has to be confirmed.** Some credentials are not a key but the email address Widgetic sends a widget's messages to (`confirmation: email_code` in `getPartnerAdapterConnections`). Saving one checks that it is one email address and emails a six-digit code to it; the answer says `awaitingConfirmation: true`, and nothing is sent to the address until the code is given back with `confirmPartnerAdapterConnection`. Saving the same address again before it is confirmed emails a new code (not sooner than a minute after the last); saving the address that is already confirmed changes nothing. If the code cannot be emailed, nothing is saved. A widget whose adapter has no key connected, or whose address is not confirmed yet, is not charged and does not run that adapter: its visitors are told the feature is unavailable, and the partner is told once a day what to do. This needs an API key with full access. The caller must be the person who administers the partner, or a Widgetic administrator. A retry is harmless: saving the same key twice only refreshes when it was set. ## OpenAPI ````yaml /openapi/widgetic-api-public.json put /partners/{partnerId}/adapter-connections/{adapterId}/{credentialKey} openapi: 3.0.0 info: title: Widgetic API Gateway version: 1.0.0 description: API documentation for the Widgetic API Gateway license: name: Widgetic Integration License url: https://docs.widgetic.com/resources/license servers: - url: https://api.widgetic.com/v1 description: Production server variables: env: default: production description: Environment apiUrl: default: https://api.widgetic.com description: API URL apiVersion: default: /v1 description: API Version path prefix security: [] tags: [] paths: /partners/{partnerId}/adapter-connections/{adapterId}/{credentialKey}: put: tags: - Partners summary: Connect an adapter key to a partner description: > Gives an adapter the key it needs to act through a service the partner has an account with, for the widgets of the customers the partner manages.
