Tools 21 found in our last check
whoamiIdentify the API key this connection uses (GET /me): `tenantId` (the workspace), `apiKeyId` and `scopes`. Write tools need the `write` scope; call this to check before attempting them.
get_usageThe workspace's plan, subscription status and this calendar month's usage against the monthly quota (GET /billing/subscription). `used`/`remaining` are null on unmetered plans. On a hard-capped plan, sends beyond the quota fail with HTTP 402 quota_exceeded.
list_channelsList the delivery channels configured in this workspace (GET /channels). Call this FIRST before sending: each entry's `id` is the `channelConfigId` for send_notification and test_send_template, `kind` is the channel type (ses_email, smtp_email, fcm_push, slack_webhook, discord_w…
send_notificationSend a notification (POST /send; needs a `write`-scoped key). Returns `{ sendId }` with HTTP 202: delivery is asynchronous, so check the outcome with get_send_status. Use exactly one mode: 1. Single: `channelConfigId` + `recipient`. 2. Fan-out: `channelConfigId` + `targets` (1-1…
get_send_statusDelivery status of a send (GET /sends/{id}): `aggregate` counts per status over the whole send (pending, claimed, delivered, failed_retryable, failed_terminal, suppressed) plus one page of per-recipient delivery rows including provider errors. Right after sending, rows are usual…
list_templatesList message templates (GET /templates): id, name, folder, channelKind, and `publishedVersionId` (null = never published, so it cannot be sent by templateId yet). Archived templates are hidden unless `includeArchived` is true. Use get_template for content and required params.
get_templateGet one template with its published version and its current draft (GET /templates/{id}): content, logTitle/logDescription, `requiredParams` a send must supply, and paramOverrides. Read this before update_template_draft, which needs the full body.
create_templateCreate a template (POST /templates; write scope). `channelKind` is permanent and must match the channels you'll send through (list_channels `templateKind`). It is saved as an unpublished draft unless `publish: true`; sending by templateId needs a published version (publish_templ…
update_template_draftReplace a template's draft (PATCH /templates/{id}; write scope). This is a full replacement, not a partial patch: pass content, logTitle, logDescription and paramOverrides as they should end up (get_template first). `name`, `folder` and `channelKind` are required for validation…
publish_templatePublish a template's current draft as its new live version (POST /templates/{id}/publish; write scope). Sends by templateId use it immediately. Fails if there is no draft or the template is archived.
archive_templateArchive a template (POST /templates/{id}/archive; write scope). Sends that reference it fail until it is restored with unarchive_template; its name stays reserved meanwhile. Confirm with the user first if it may be in production use.
unarchive_templateRestore an archived template (POST /templates/{id}/unarchive; write scope). This is how to reclaim a name held by an archived template instead of creating a new one.
test_send_templateSend a real test of a template's PUBLISHED version to one recipient (POST /templates/{id}/test-send; write scope). It goes through the provider for real, so use a recipient the user controls. Test sends don't count toward the monthly quota (a small daily allowance applies instea…
list_feed_notificationsRead one end user's in-app notification feed (GET /notifications): the entries created by sends with `feed` or `showInFeed`. This is what an in-app inbox would show, not delivery status (use get_send_status for that). Paginate by passing `nextCursor` back as `cursor`.
get_click_statsEmail link click counts grouped by destination URL (GET /clicks) for a `sendId`, a `campaignId`, or both (at least one is required). Only links from email sends made with `trackClicks: true` are counted.
list_webhooksList the workspace's outbound event webhooks (GET /tenant-webhooks): url, subscribed events, enabled flag and delivery health (consecutiveFailures, lastError). Signing secrets are never returned.
get_webhookGet one outbound webhook (GET /tenant-webhooks/{id}) including its delivery health (consecutiveFailures, lastDeliveryAt, lastFailureAt, lastError).
create_webhookCreate an outbound webhook that Ray POSTs signed event payloads to (POST /tenant-webhooks; write scope; Pro plan or higher, otherwise 403). The URL must be public HTTPS. The response contains the signing `secret` exactly once: show it to the user to store (e.g. as an env var), s…
update_webhookChange a webhook (PATCH /tenant-webhooks/{id}; write scope). Only the fields you pass change; pass at least one. `rotateSecret: true` issues a new signing secret, returned once in the response, and the old secret stops verifying immediately, so the receiving service must be upda…
delete_webhookDelete (archive) a webhook so it receives no more events (DELETE /tenant-webhooks/{id}; write scope). It cannot be restored through the API; confirm with the user first.
read_docsRead Ray's documentation as markdown. With no `slug` it returns the index (llms.txt) listing every page; then pass a page slug, i.e. the path after /docs/ without `.md`, such as `sending`, `templates`, `idempotency`, `errors`, `rate-limits`, `webhooks`, `status-and-feeds` or `ch…
