Connectors

Connectors are the actions side of integrations — they let your agents and workflows perform actions on external services: send data, execute operations, or query information.

Connectors require credentials for authentication. Set up your credentials first before creating a connector.

Overview

Connectors are managed in Application > Integrations > Connectors. Each connector links a credential to an external service, giving your agents and workflows runtime access.

  to act              via connector        or service

Connector Categories

Each connector belongs to a node category. See Integration Nodes for detailed per-node documentation.

Category	Nodes	Description
Databases	PostgreSQL, Oracle	Query, read, and write to relational databases
APIs & Protocols	REST, GraphQL, SOAP, OpenAPI	Call external APIs using standard protocols
Email & Messaging	Gmail, Telegram, WhatsApp, SMTP	Send messages, manage inboxes, bot integration
CRM & Sales	amoCRM, Bitrix24	Customer management, sales pipeline automation
Productivity	Linear, Google Calendar	Issue tracking, scheduling, project management
Documents	Carbone, Digital Sign, Outline	Document generation, signatures, knowledge base
File Transfer	SFTP, FTP/FTPS	Secure file upload, download, and transfer
Message Queues	Kafka, RabbitMQ	Event streaming, async message processing
Government	eGov Gateway	Kazakhstan SmartBridge integration
Weather	OpenWeather	Weather data and forecasting
AI & LLM	LLM providers	AI model integration and inference

Creating a Connector

Navigate to Application > Integrations > Connectors
Click the "Create connector" button
Select the connector type (e.g., PostgreSQL, REST API, Telegram)
Enter a name and optional description
Enter connection details (token, host, URL — depends on connector type)
Click Create

Create connector dialog

Configuration Fields

Field	Required	Description
Connector Type	Yes	The external service type to connect to
Name	Yes	Descriptive identifier (e.g., "My Telegram Bot")
Description	No	Optional notes about this connector

The remaining fields under Main options depend on the selected connector type. For example:

Telegram — Token
PostgreSQL — Host, Port, User, Password, Schema, Database
REST API — URL, Headers
GraphQL — URL, Headers, Insecure Skip Verify

Managing Connectors

Viewing Connectors

The Connectors tab displays a table with all connectors in the current application:

Connectors list view

Column	Description
Connector Name	Connector identifier
Description	Optional description
Resource	Connector type (e.g., `axellero.nodes.telegram`)
Created At	When the connector was created

Editing a Connector

Click the edit icon on the connector row
Update the fields as needed
Click Update

Edit connector dialog

Changing connection details may temporarily disrupt agents and workflows that use this connector. Update during low-traffic periods when possible.

Deleting a Connector

Click the delete icon on the connector row
Confirm the deletion in the confirmation dialog

Delete connector confirmation

Deleting a connector will break any triggers and workflow nodes that depend on it. Remove dependent triggers first, then delete the connector.

Troubleshooting

Error	Cause	Solution
"Connection refused"	Host unreachable or wrong port	Verify host, port, and network access
"Authentication failed"	Invalid credential	Check the linked credential is correct and not expired
"Connection timed out"	Network or firewall issue	Verify network access; increase connection timeout if needed
"SSL certificate error"	Untrusted or expired certificate	Update the certificate, or disable SSL verification for dev environments
"Too many connections"	Connection pool exhausted	Reduce concurrent usage or increase pool limits on the service side
"Schema discovery failed"	Insufficient permissions	Grant the required read permissions on the target database

Credentials — Set up authentication before creating connectors
Triggers — Configure real-time event handling for your connectors
MCP Servers — Connect to MCP-compatible tool servers
