CRM
Connect HubSpot
Your application calls one EchoRelay URL. When HubSpot changes its API, you update the mapping, not your application.
How HubSpot signs requests
A private app access token, sent as a bearer token in the Authorization header.
Can you connect it today?
Yes, with a private app. Add a bearer-token credential with its access token.
A sample mapping
Your application sends the first request below. The mapping turns it into the body of POST /crm/v3/objects/contacts, shown second.
Your request
{
"email": "ana@example.com",
"firstName": "Ana",
"lastName": "Silva"
}
What HubSpot receives
{
"properties": {
"email": "ana@example.com",
"firstname": "Ana",
"lastname": "Silva"
}
}
The mapping
{
"$schema": "https://schemas.echorelay.dev/transform/mapping/v1.json",
"root": {
"type": "object",
"id": "root",
"properties": {
"properties": {
"type": "object",
"id": "props",
"properties": {
"email": {
"type": "field",
"id": "email",
"path": "email"
},
"firstname": {
"type": "field",
"id": "first-name",
"path": "firstName"
},
"lastname": {
"type": "field",
"id": "last-name",
"path": "lastName"
}
}
}
}
}
}
The grammar, the answer mapping and the dry run are in the mapping docs.
What you bring
This is not a ready-made connector. You bring a sample request or HubSpot’s OpenAPI document, you or your agent write the mapping, and we run the integration you define.
