Nodes

Pachca

Main node for interacting with the Pachca API. Supports 18 resources and 65+ operations:

| Resource | Operations | |----------|-----------| | Bot | Update, Get Many Events, Remove Events | | Chat | Create, Get, Get Many, Update, Archive, Unarchive | | Chat Export | Create, Get | | Chat Member | Get Many, Create, Delete, Update, Leave, Add/Remove Group Tags | | Custom Property | Get | | File | Create (S3 two-stage upload) | | Form | Create (visual builder, templates, or JSON) | | Group Tag | Create, Get, Get Many, Update, Delete, Get Many Users | | Link Preview | Create | | Message | Create, Get, Get Many, Update, Delete, Pin, Unpin | | Profile | Get Info, Get, Update/Delete Avatar, Get/Update/Delete Status | | Reaction | Create, Delete, Get Many | | Read Member | Get Many | | Search | Chats, Messages, Users | | Security | Get Many | | Task | Create, Get, Get Many, Update, Delete | | Thread | Create, Get | | User | Create, Get, Get Many, Update, Delete, Update/Delete Avatar, Get/Update/Delete Status |

Pachca Trigger

Webhook-based trigger that listens for 16 Pachca event types:

| Category | Events | |----------|--------| | Messages | new, updated, deleted | | Reactions | new, deleted | | Interactive | button pressed, form submitted, link shared | | Chat members | added, removed | | Users | invited, confirmed, activated, suspended, updated, deleted | | Wildcard | all events |

Automatically registers webhooks via the Bot API when workflow is activated. Deactivation removes the webhook.

Credentials

Create a Pachca API credential with:

| Field | Required | Description | |-------|----------|-------------| | Base URL | no | Default: https://api.pachca.com/api/shared/v1. Change only for on-premise. | | Access Token | yes | Bot or personal API token | | Bot ID | no | For automatic webhook registration in Trigger. Auto-detected from bot tokens. Set explicitly for admin tokens. | | Signing Secret | no | For HMAC-SHA256 verification of incoming webhooks (pachca-signature header) | | Webhook Allowed IPs | no | Comma-separated IPs allowed to send webhooks. Pachca sends from 37.200.70.177. Empty = allow all. |

Where to get tokens:

• Bot token — Bot settings > API tab
• Personal token — Settings > Automations > API

Credentials are tested by calling GET /oauth/token/info.

Key Features

Pagination

All list operations (Get Many) support automatic cursor-based pagination:

• Return All = true — fetches all pages automatically
• Return All = false — returns up to Limit results (default: 50)

Simplify

Toggle Simplify (on by default) to return only key fields from API responses. Turn off for full response.

• Message — id, entity_id, chat_id, content, user_id, created_at
• Chat — id, name, channel, public, members_count, created_at
• User — id, first_name, last_name, nickname, email, role, suspended
• Task — id, content, kind, status, priority, due_at, created_at

Searchable Dropdowns

Chat ID and User ID fields support search by name — type to find instead of entering numeric IDs.

Message Buttons

Create messages with interactive buttons via JSON:

[[{"text": "Approve", "data": "approve"}, {"text": "Reject", "data": "reject"}]]

Button types: URL (opens link) and Data (sends button_pressed webhook event).

Forms

Create modal forms with three builder modes:

• Visual Builder — add blocks (text input, select, radio, checkboxes, date/time, file upload)
• Templates — predefined forms (Feedback, Time Off, Survey, Bug Report)
• JSON — paste blocks from the visual playground

Forms require a trigger_id from a button_pressed webhook event (valid for 3 seconds).

Avatar Upload

Upload avatar images for profiles and users via multipart/form-data. Uses binary data from a previous node (HTTP Request, Read Binary File). The Input Binary Field parameter (default: data) specifies which binary property contains the image.

File Upload

Two-stage S3 upload with automatic retry. Sources: URL or Binary Data from previous workflow nodes.

AI Tool Use

Both nodes have usableAsTool: true — they can be used as tools for AI Agent nodes in n8n.

Error Handling

• 5xx/429 retry — exponential backoff with jitter, respects Retry-After header (up to 5 attempts)
• continueOnFail — supported on all operations

v1 Compatibility

Version 2 is fully backward compatible with v1. Existing v1 workflows continue to work without modification.

The node uses the VersionedNodeType pattern with defaultVersion: 2:

• Existing nodes keep typeVersion: 1 with v1 UI and parameter names
• New nodes get typeVersion: 2 with cleaner naming and new resources
• A shared router translates v1 names to v2 at runtime

Renamed resources: reactions → reaction, status → profile, customFields → customProperty

Renamed operations: send → create, getById → get, addReaction → create, etc.

New v2 resources: Chat Member, Custom Property, Read Member, Link Preview, Search, Chat Export, Security

To upgrade a v1 node: delete it, add a new Pachca node (defaults to v2), reconfigure with v2 names. API calls are identical.

Usage Examples

Send a message

Set Resource = Message, Operation = Create:

• Entity ID — chat ID (use searchable dropdown or enter number)
• Content — message text (supports Markdown)

Send a message with buttons

Set Resource = Message, Operation = Create, then in Additional Fields add Buttons:

[[{"text": "Approve", "data": "approve"}, {"text": "Reject", "data": "reject"}]]

When a user clicks a Data button, the Pachca Trigger node receives a button_pressed event with the button's data value.

Upload a file and attach to message

1. Pachca (File > Create) — upload file from URL or binary data, get key in response
2. Pachca (Message > Create) — send message with the file key in the files field

Search and process results

Set Resource = Search, Operation = Get Many Messages:

• Query — search text
• Return All = false, Limit = 10

Open a modal form

1. Pachca Trigger — event Button Pressed (provides trigger_id)
2. Pachca (Form > Create) — set Title, Trigger ID, choose builder mode
3. Pachca Trigger — event Form Submitted (in a separate workflow)

Bot echo workflow

1. Pachca Trigger — event New Message
2. IF — filter: message.user_id ≠ bot ID
3. Pachca (Message > Create) — echo the message back

Troubleshooting

401 Unauthorized

Token is invalid or expired. Check Access Token in Credentials. For bot tokens: Bot settings > API tab. For personal tokens: Settings > Automations > API.

403 Forbidden

Token lacks required scopes for this operation. Check available scopes in your token settings. Admin operations (managing users, tags, security log) require admin-level scopes.

429 Too Many Requests

Rate limit exceeded (~4 req/sec for messages, ~50 req/sec for other operations). The node retries automatically with exponential backoff. For bulk operations, add a Wait node between steps.

Webhook not received (Trigger)

1. Bot not in chat — bot only receives events from chats it's a member of
2. Workflow not activated — click Activate in the top right
3. Bot ID missing — set Bot ID in Credentials for auto-registration, or configure webhook URL manually in bot settings
4. n8n not reachable — Pachca can't send webhooks to localhost. Use a tunnel (ngrok, Cloudflare Tunnel) or deploy to a server with a public IP

Form not opening

trigger_id from a button_pressed event expires in 3 seconds. Place the Form > Create node immediately after the Trigger, with no Wait nodes or long operations in between.

Node not showing in n8n

1. Restart n8n after installing the package
2. Check n8n logs for loading errors
3. Verify the package is in the correct directory (~/.n8n/nodes/ or ~/.n8n/custom/node_modules/)
