MCP

Give your agent change.photos tools

Every change.photos action is exposed as an MCP tool on Pipedream's remote server. Point a client at it with your end user's ID and Connect resolves that user's change.photos account for each tool call — you store no tokens.

API PROXY

Call the change.photos API directly

For an endpoint with no pre-built tool, the Connect proxy forwards your request to the change.photos API with the connected user's credentials attached. You store no tokens and write no refresh logic.

Pipedream Connect

const resp = await pd.proxy.get({
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  accountId: "apn_xxxxxxx",
  url: "https://www.change.photos/api/change",
})

// Any allowed change.photos endpoint works here. Pipedream attaches the
// connected account's credentials to the outgoing request.

# The path segment is the target URL, URL-safe base64 encoded:
# https://www.change.photos/api/change

curl "https://api.pipedream.com/v1/connect/{project_id}/proxy/aHR0cHM6Ly93d3cuY2hhbmdlLnBob3Rvcy9hcGkvY2hhbmdl?external_user_id={external_user_id}&account_id=apn_xxxxxxx" \
  -H "Authorization: Bearer {access_token}" \
  -H "x-pd-environment: production"

SDK

Run change.photos actions from your backend

Connect a user's change.photos account once, then run Transform Image on their behalf from your own code — TypeScript, Python, or plain HTTP.

Pipedream Connect

import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "change_photos-transform-image",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    change_photos: { authProvisionId: "apn_xxxxxxx" },
    imageUrl: "Image URL",
    width: 10,
  },
})

from pipedream import Pipedream

pd = Pipedream(
    client_id="{oauth_client_id}",
    client_secret="{oauth_client_secret}",
    project_id="{project_id}",
    project_environment="production",
)

result = pd.actions.run(
    id="change_photos-transform-image",
    external_user_id="{external_user_id}",  # any stable ID for this user in your system
    configured_props={
        "change_photos": {"authProvisionId": "apn_xxxxxxx"},
        "imageUrl": "Image URL",
        "width": 10,
    },
)
