The secrets module lets automations securely store and retrieve sensitive values (API keys, tokens, credentials) at runtime. Values are encrypted at rest and never exposed as plaintext in automation outputs or logs. This page documents two things:
  • The runtime API (secrets.set, secrets.get, secrets.delete) for automations.
  • The Settings → Secrets form in the Builder UI, which is where workspace-level secrets are typically configured before any automation runs.

Settings → Secrets form

Open Settings → Secrets in the Builder. The form has two sections.

Schema-defined secrets

The top section is generated from the workspace’s secret schema, declared in index.yml:
Every property of the schema is rendered as an input field. These are the “main” secrets of the workspace: they have known names, automations reference them as {{secret.<name>}}, and someone (usually the workspace author) committed the schema to source control. Typing a value and clicking Save Secrets posts the new values to POST /workspaces/{id}/secrets. Values are stored encrypted; the form never reads back plaintext (an empty field means “leave the existing value untouched”, not “clear the value”).

Additional Secrets form

The “Additional Secrets” section underneath is for secrets that are not declared in the schema. The label “Additional” is intentional: these are extras beyond the schema-defined set. Use the Additional form when:
  • You are prototyping and have not yet committed a schema.
  • You need an environment-specific override (e.g. a per-deploy webhook URL) that should not appear in source.
  • You want a one-off value usable from a single automation without touching index.yml.
Once a name stabilizes, promote it to the schema so the next workspace clone has the documentation built in.
The “Additional Secrets” form persists plaintext values to the workspace’s encrypted secret store. It is not a temporary scratchpad; entries survive reloads and pulls (unless overwritten by a pulled index.yml).

Runtime API

For automations that need to create or rotate secrets at runtime (OAuth tokens, refresh tokens, per-user credentials), the secrets module exposes set, get, and delete.

How it works

  1. secrets.set and secrets.get return an opaque secret reference (a $secret:... string), not the actual value.
  2. When this reference is used inside a fetch instruction (in the URL, headers, body, query, or auth fields), the platform automatically resolves it to the real value just before the HTTP call.
  3. The resolved value is redacted from all logs and events.
Secret references are short-lived (a few minutes). Always call secrets.get right before using the reference; do not store it for later reuse.

Scopes

Functions

set: Store or update a secret

Returns a $secret:... reference string. If a secret with the same name and scope already exists, it is updated.

get: Retrieve a secret reference

Returns a $secret:... reference string, or { error: "not_found" } if the secret does not exist (or has expired).

delete: Remove a secret

Returns { deleted: true } on success, or { error: "not_found" }.

Using secret references in fetch

Pass the reference returned by set or get wherever a sensitive value is needed in a fetch instruction. The platform resolves it transparently:
Resolution is supported in these fetch fields: url, headers, body, query, and auth (including auth.awsv4).
Secret references expire after a few minutes. Always retrieve the reference (secrets.get) in the same automation run where you use it.

Error handling

All three functions return an error object instead of throwing when the error is actionable: Use onError or a conditions block to handle these:
