Full document replacement — include all nodes and properties in the body, the trigger included; anything omitted is deleted. The journey stays a draft; making the change live is a separate step this tool cannot perform. This is where send, delay, branch and exit nodes are added, and send node template IDs must already be scoped to this journey. The result carries a "verification" object read back from the server after the write — check it every time. verified:true means what you asked for is what saved. verified:false names what did not: "fieldMismatches" for node fields that failed to land, "nodeCountMismatch" for a node dropped or added, and "unknownTemplateReferences" for a send node pointing at a template id this journey does not have — almost always a mistyped id, so re-copy it from the create_journey_template or get_journey response it came from. Fix the specific thing named and send the corrected document. Re-sending an identical call changes nothing, and every replace_journey overwrites the whole draft again.

Description, as the server wrote it: ```untrusted-server-text Create a new journey. Always created as a draft; making it live is a separate step this tool cannot perform. Send two nodes: the trigger, and an exit node last. Both are required — a create with no exit node is rejected, and the API reports that as "exit node must be the last node in the journey" even when no exit was sent at all. Send and delay nodes are added afterwards by replace_journey, once journey-scoped templates exist. Node ids are server-generated; do NOT include an id field. Example: { name: "Welcome Journey", nodes: [{ type: "trigger", trigger_type: "api-invoke" }, { type: "exit" }], enabled: true }. The result carries a "verification" object read back from the server after the write — check it every time. verified:true means what you asked for is what saved. verified:false names what did not: "fieldMismatches" for node fields that failed to land, "nodeCountMismatch" for a node dropped or added, and "unknownTemplateReferences" for a send node pointing at a template id this journey does not have — almost always a mistyped id, so re-copy it from the create_journey_template or get_journey response it came from.

Description, as the server wrote it: ```untrusted-server-text Create a notification template scoped to a journey. Always created as a draft; making it live is a separate step this tool cannot perform. The template can then be referenced in journey send nodes. content.elements must be wrapped in a channel block — the API rejects bare elements. Example: { journey_id: "j-abc", channel: "email", notification: { name: "Welcome Email", tags: [], brand: null, subscription: null, content: { version: "2022-01-01", elements: [{ type: "channel", channel: "email", elements: [{ type: "text", content: "Hello!" }] }] } } }. The result carries a "verification" object confirming the new id is really present on the journey. verified:true means the id in this response is safe to reference from a send node. verified:false means it is not visible yet — re-read the journey before referencing it, and do not create a second template to work around it. An "errorKind" of "unauthorized" means the template was created and only the check was refused. ``` ### `create_list` - The name "create_list" says "create": a word for a change.

Choosing the window — supply EITHER `lookback` OR `start` and `end` together, NEVER both. Supplying both is rejected. For a relative window like 'the last week', `lookback` alone is the whole answer: do not also pin `start` and `end`. Default is the last 30 days by day. Fine granularities cover shorter windows: HOUR spans at most 7 days and DAY at most 90. How far back a workspace may look also depends on its plan; a request reaching further back is refused with a payment error, which means the plan does not cover that window, NOT that there is no data. A coarser granularity can reach further back than a fine one. Reading the numbers correctly: - The first four counters are NESTED, not separate groups. Every delivered message is also counted in sent, every opened one in delivered, every clicked one in opened. So sent >= delivered >= opened >= clicked always. Report rates (delivered/sent) or the counters themselves. Do NOT add them together — the total is meaningless. And sent minus delivered is NOT a failure count; it is only 'did not reach the delivered stage', for any reason. - errors and undeliverable are counted separately and OVERLAP the funnel: a message that failed on one provider and succeeded on a retry appears in both errors and sent. They are not a remainder and do not complete a total. - Every counter is a count of distinct MESSAGES, not of events. A message that errored three times counts once in errors. - A bucket's `data` array holds one entry per provider and channel. To get a bucket total, add up the entries in that array — that is the only sum that means anything here. Note that rows for Courier's own built-in email sender are excluded, so these entries can add up to less than the workspace's true volume. What the buckets mean: - A message is counted in the bucket it was ENQUEUED in, not when the event happened. An open today of a message sent last Tuesday is counted in last Tuesday's bucket. So a past bucket can still change: yesterday's `opened` may be higher when you ask again tomorrow. - Results are cached for up to an hour and the pipeline adds its own lag, so a message sent minutes ago is expected NOT to appear yet. Never tell a user a just-sent message is missing; say the data has not caught up. - Read the window off the response's `start` and `end`, not off what you asked for. The API widens the window to whole buckets and returns the boundaries it actually used. - Quiet buckets are returned with an empty `data` array, so the series has no gaps. - An unknown template id returns an all-empty series rather than an error, and messages sent without a template never appear here at all. An empty result is not proof a template is unused — check that the id is right before concluding anything from it. - Because of that, a NOT FOUND / 404 error is never about the template id. It means the metrics endpoint itself could not be reached, which is an infrastructure or configuration problem on Courier's side. Say that the metrics service is unreachable and that someone should be told; do NOT tell the user to check or correct their template id, which sends them to fix something that was never wrong. ``` ### `get_preference_section` - The name "get_preference_section" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get one preference section by ID, including its topics.

Description, as the server wrote it: ```untrusted-server-text Get one subscription topic within a section, including its default opt-in state. Returns 404 if the section or topic does not exist, or if the topic belongs to a different section — so a 404 here can mean the pairing is wrong rather than the topic missing. ``` ### `get_preview_device_set` - The name "get_preview_device_set" says "get": a word for reading.

Description, as the server wrote it: ```untrusted-server-text List configured provider integrations for the workspace. ``` ### `list_routing_strategies` - The name "list_routing_strategies" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the workspace's routing strategies, returning metadata only. A routing strategy decides which channel a notification takes and in what order.

Description, as the server wrote it: ```untrusted-server-text List the workspace's tenants. A tenant is a customer or organisation whose users, branding and preferences are scoped separately; this answers "what tenants do I have" and gives you the tenant IDs get_tenant needs. ``` ### `list_user_push_tokens` - The name "list_user_push_tokens" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List all push/device tokens for a user. ``` ### `list_user_tenants` - The name "list_user_tenants" says "list": a word for reading.
