Trimble

Leaf connects to Trimble Agriculture using OAuth 2.0. Once connected, Leaf syncs growers, farms, fields, machine files, and field operations for the Leaf user.

Prerequisites

A Trimble Agriculture developer account. Register here.
Your application’s clientId and clientSecret from Trimble.
A grower’s refreshToken obtained through the Trimble OAuth 2.0 consent flow.

Setup steps

Complete the Trimble OAuth 2.0 flow to obtain a refreshToken for the grower’s account.
POST the credentials to Leaf:

curl -X POST \
    -H 'Authorization: Bearer YOUR_TOKEN' \
    -H 'Content-Type: application/json' \
    -d '{
      "clientId": "your-client-id",
      "clientSecret": "your-client-secret",
      "refreshToken": "grower-refresh-token"
    }' \
    'https://api.withleaf.io/services/usermanagement/api/users/{leafUserId}/trimble-credentials'

import requests

TOKEN = 'YOUR_TOKEN'

endpoint = 'https://api.withleaf.io/services/usermanagement/api/users/{leafUserId}/trimble-credentials'
headers = {'Authorization': f'Bearer {TOKEN}'}

data = {
    "clientId": "your-client-id",
    "clientSecret": "your-client-secret",
    "refreshToken": "grower-refresh-token"
}

response = requests.post(endpoint, headers=headers, json=data)
print(response.json())

const axios = require('axios')
const TOKEN = 'YOUR_TOKEN'

const endpoint = 'https://api.withleaf.io/services/usermanagement/api/users/{leafUserId}/trimble-credentials'
const headers = { 'Authorization': `Bearer ${TOKEN}` }

const data = {
    "clientId": "your-client-id",
    "clientSecret": "your-client-secret",
    "refreshToken": "grower-refresh-token"
}

axios.post(endpoint, data, { headers })
    .then(res => console.log(res.data))
    .catch(console.error)

Leaf validates the token and begins syncing. Check credential status with GET /users/{leafUserId}/trimble-credentials.

Credentials schema

Create request body:

Field	Type	Required	Description
`clientId`	string	Yes	Your application’s client ID from Trimble
`clientSecret`	string	Yes	Your application’s client secret
`refreshToken`	string	Yes	The grower’s OAuth refresh token

Response:

{
  "id": "uuid",
  "status": "str",
  "createdTime": "yyyy-MM-dd'T'HH:mm:ss.SSSSSS'Z'",
  "tokenMetadata": {"scopes": ["str"]},
  "clientId": "str",
  "clientSecret": "str",
  "accessToken": "str",
  "refreshToken": "str"
}

Endpoints

Base URL: https://api.withleaf.io/services/usermanagement/api

Action	Method	Path
Get credentials	GET	`/users/{leafUserId}/trimble-credentials`
Create credentials	POST	`/users/{leafUserId}/trimble-credentials`
Delete credentials	DELETE	`/users/{leafUserId}/trimble-credentials`
Get credential events	GET	`/users/{leafUserId}/trimble-credentials/events`

Troubleshooting

Use the events endpoint to inspect credential health:

curl -X GET \
    -H 'Authorization: Bearer YOUR_TOKEN' \
    'https://api.withleaf.io/services/usermanagement/api/users/{leafUserId}/trimble-credentials/events'

import requests

TOKEN = 'YOUR_TOKEN'
endpoint = 'https://api.withleaf.io/services/usermanagement/api/users/{leafUserId}/trimble-credentials/events'
headers = {'Authorization': f'Bearer {TOKEN}'}

response = requests.get(endpoint, headers=headers)
print(response.json())

const axios = require('axios')
const TOKEN = 'YOUR_TOKEN'

const endpoint = 'https://api.withleaf.io/services/usermanagement/api/users/{leafUserId}/trimble-credentials/events'
const headers = { 'Authorization': `Bearer ${TOKEN}` }

axios.get(endpoint, { headers })
    .then(res => console.log(res.data))
    .catch(console.error)

Event logs are retained for 30 days. Once the credential is deleted or disassociated from the Leaf user, the logs are no longer available.

Common issues:

Status changes to invalid: The grower may have revoked access or the refresh token expired. Have the grower re-authorize through Trimble’s OAuth flow.
