+      description: |
+        You can create an API template source to import a knowledge base through its vendor's REST API. Send a template that describes the vendor's API, values for the template's variables, and a token for the vendor's API.
+
+        Intercom checks the template and the variables, then checks the token by requesting the template's tree from the vendor. If any check fails, the source isn't created and the API returns a `422` error that names each failing field. Otherwise, the source is created and its first sync starts. The imported content is filed in a folder named after the template.
+
+        If the first sync can't start, the source is still created. Its `latest_sync` is then `null` or has the status `failed`, and you can start a sync with `POST /ai/api_template_sources/{id}/sync`.
+
+        The token is stored with the source and is never returned.
+
+        OAuth tokens must have the `read_write_ai_content` scope.

+            The template, the variables or the token failed a check, and the source wasn't created. The response can list several errors.
+
+            Each error's `field` names the request field that failed, such as `template.base_url`, `variables.space_id` or `auth_token`. A missing value has the code `parameter_not_found`, and any other failure has the code `parameter_invalid`.
+
+            When a template check fails, the message names the check: `<field> fails the <check> check`. The checks are listed in the API Template schema. A tree response over 25 MB fails on `template.tree` with the message `<name>'s tree response is too large: over the 25 MB cap`, where `<name>` is the template's name.
+
+            If the vendor answers the token check with `401` or `403`, the error is on `auth_token` with the message `<name> rejected the token`. If it answers with anything other than success, `401` or `403`, such as a `404` on `tree.path`, a redirect, a `429`, a `5xx` or a timeout, the error is on `auth_token` with the message `<name> could not be reached to check the token`. The check isn't retried.

+        A source runs one sync at a time. Intercom also syncs each source automatically, about once a day, unless the vendor has rejected the token, so you only need this endpoint to sync sooner.

+      description: |
+        An API template describes how to read a knowledge base through its vendor's REST API. Intercom requests the `tree`, a list of the knowledge base's nodes, such as folders and pages. For each node that is content, it then requests the `item`, such as the page's body. `mapping` says which fields of the node and the item become the imported content.
+
+        A placeholder such as `{space_id}` in `base_url`, a path or a query value is filled from `variables`. In the item request, it can also be filled from `item.node_values`. Values filled into `base_url` or a path are URL-encoded. `{token}` stands for the source's token. It can only be used in `auth.value` or as an entire query value.
+
+        When a template check fails, creating the source returns a `422` error whose message is `<name> fails the <check> check`, where `<name>` is the failing field below; see the create endpoint for the error shape. Each field below names its checks in brackets. Top-level keys other than the ones below are ignored and not stored.
+
+        Intercom sends one tree request per sync. Paging isn't supported. A sync fails if the tree response is over 25 MB or has more than 50,000 nodes. Nodes nested more than 12 levels deep aren't imported. An item whose response is over 10 MB, or that the vendor returns as not found, is skipped. A redirect isn't followed and fails the sync. During a sync, if the vendor answers `429`, Intercom waits for the time in its `Retry-After` header, or 60 seconds if there's none, and then retries. If the vendor keeps answering `429`, the sync fails.
