External Automation IntegrationNEW
With Sellio’s webhooks and REST API, you connect the CRM to Zapier, Make or n8n and build automations across thousands of external tools. When something happens in the CRM, an action fires in another system, and vice versa. Automate the repetitive work without writing a line of code.
- Webhooks that fire when something happens in the CRM.
- A REST API to create and update records from the outside.
- Ready-made connection with Zapier, Make and n8n.
Free in Sellio, you only pay for the machine
Webhooks and REST API included: you only pay for the machine and your automation account.
No-code automation
Build flows by dragging blocks in Zapier, Make or n8n, without needing a developer for every integration.
Thousands of apps within reach
Connect the CRM to chat, email marketing, spreadsheets, ERPs and whatever else your operation uses.
Less repetitive work
Manual copy-paste between systems disappears, freeing the team for what matters.
Protected keys
The API tokens stay in an encrypted vault and are never shown in the interface.
Bring your own automation account: the API keys and tokens stay vaulted and never appear on screen.
Open by default → webhooks + REST follow market standards, with no lock-in to a single platform.
Best-effort with re-delivery: if a webhook fails, the CRM carries on and the automation resumes.
The CRM at the center of your ecosystem
Every new opportunity, contact or stage change can fire a webhook that triggers Zapier, Make or n8n. From there the sky’s the limit: post a message in your team chat, create a task in another tool, update a spreadsheet or notify finance, all with no manual intervention.
From the outside in, too
The REST API lets external systems create and update records in Sellio. A website form, an e-commerce order or a campaign lead lands straight in the CRM as a new deal, ready for the team to act on.
- 1
Connect your Zapier, Make or n8n account using the REST API → the tokens go to the vault.
- 2
Choose the CRM events that should fire webhooks.
- 3
Build the flow in your automation tool.
- 4
The automations start running on their own, in both directions.
New lead becomes a task
A website form creates a deal via the API, and a webhook fires a Zapier task for the rep on duty.
Alert in team chat
When a big deal is won, Make posts a celebratory message in the team channel automatically.
Sync with the ERP
When a deal is marked paid, n8n sends the data to the ERP to generate the invoice, with no double entry.
Do I need to know how to code?
No. You build the automations by dragging blocks in Zapier, Make or n8n, without needing a developer.
What if a webhook fails?
The CRM keeps working normally and the automation resumes, since webhooks run best-effort with re-delivery.
Which external automation tools are supported?
Zapier, Make and n8n already have a ready-made connection with Sellio.
How does the CRM tell other systems something happened?
Webhooks fire when something happens in the CRM, like a new opportunity, contact or stage change.
Can external systems create records in Sellio?
Yes. The REST API lets external systems create and update records in the CRM, like website forms or e-commerce orders.
Are my API keys exposed on screen?
No. API keys and tokens stay in a vault and never appear in the interface.
Does this lock me into a single automation platform?
No. Webhooks and the REST API follow market standards, so there's no lock-in to a single tool.
Can I connect the CRM to spreadsheets and ERPs?
Yes. You connect the CRM to chat, email marketing, spreadsheets, ERPs and whatever else your operation uses, via Zapier, Make or n8n.
Is the automation account mine or Sellio's?
It's your own automation account; you bring your own keys and tokens, which stay in the vault.
