Use predefined connections to allow users to access your piece in the embedded app without re-entering authentication credentials. The high-level steps are:
  • Create a global connection for a project using the API in the platform admin. Only platform admins can edit or delete global connections.
  • (Optional) Hide the connections dropdown in the piece settings.

​
Prerequisites

​
Create a Predefined Connection

1

Create an API Key

Go to Platform Admin → Security → API Keys and create an API key. Save it for use in the next step.Create API Key
2

Create a Global Connection via API

Add the following snippet to your backend to create a global connection each time you generate the JWT token.The snippet does the following:
  • Create Project If it doesn’t exist.
  • Create a global connection for the project with certain naming convention.
const apiKey = 'YOUR_API_KEY';
const instanceUrl = 'https://cloud.activepieces.com';

// The name of the user / organization in your SAAS
const externalProjectId = 'org_1234';
const pieceName = '@activepieces/piece-gelato';
// This will depend on what your piece auth type is, can be one of this ['PLATFORM_OAUTH2','SECRET_TEXT','BASIC_AUTH','CUSTOM_AUTH']
const pieceAuthType = "CUSTOM_AUTH"
const connectionProps = {
    // Fill in the props required by your piece's auth
}
const { id: projectId, externalId } = await getOrCreateProject({
  projectExternalId: externalProjectId,
  apiKey,
  instanceUrl,
});

await createGlobalConnection({
  projectId,
  externalProjectId,
  apiKey,
  instanceUrl,
  pieceName,
  props,
  pieceAuthType
});
Implementation:
async function getOrCreateProject({
    projectExternalId,
    apiKey,
    instanceUrl,
}: {
    projectExternalId: string,
    apiKey: string,
    instanceUrl: string
}): Promise<{ id: string, externalId: string }> {

    const projects = await fetch(`${instanceUrl}/api/v1/projects?externalId=${projectExternalId}`, {
        method: 'GET',
        headers: {
            'Authorization': `Bearer ${apiKey}`,
            'Content-Type': 'application/json'
        },
    })
        .then(response => response.json())
        .then(data => data.data)
        .catch(err => {
            console.error('Error fetching projects:', err);
            return [];
        });

    if (projects.length > 0) {
        return {
            id: projects[0].id,
            externalId: projects[0].externalId
        };
    }

    const newProject = await fetch(`${instanceUrl}/api/v1/projects`, {
        method: 'POST',
        headers: {
            'Authorization': `Bearer ${apiKey}`,
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            displayName: projectExternalId,
            metadata: {},
            externalId: projectExternalId
        })
    })
        .then(response => response.json())
        .catch(err => {
            console.error('Error creating project:', err);
            throw err;
        });

    return {
        id: newProject.id,
        externalId: newProject.externalId
    };
} 

async function createGlobalConnection({
    projectId,
    externalProjectId,
    apiKey,
    instanceUrl,
    pieceName,
    props,
    pieceAuthType
}: {
    projectId: string,
    externalProjectId: string,
    apiKey: string,
    instanceUrl: string,
    pieceName: string,
    props: Record<string, any>,
    pieceAuthType
}) {

    const displayName = 'Gelato Connection';
    const connectionExternalId = 'gelato_' + externalProjectId;

    return fetch(`${instanceUrl}/api/v1/global-connections`, {
        method: 'POST',
        headers: {
            'Authorization': `Bearer ${apiKey}`,
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            displayName,
            pieceName,
            metadata: {},
            type: pieceAuthType,
            value: {
                type: pieceAuthType,
                props
            },
            scope: 'PLATFORM',
            projectIds: [projectId],
            externalId: connectionExternalId
        })
    });
}

​
Hide the Connections Dropdown (Optional)

1

Modify Trigger / Action Definition

Wherever you call createTrigger or createAction set requireAuth to false, this will hide the connections dropdown in the piece settings in the builder, next we need to fetch it based on a naming convention.
2

Fetch the connection

Here is example how you can fetch the connection value based on naming convention, make sure this naming convention is followed when creating a global connection.
import {
   ConnectionsManager,
   Property,
   TriggerStrategy
} from "@activepieces/pieces-framework";
import {
   createTrigger
} from "@activepieces/pieces-framework";
import {
   isNil
} from "@activepieces/shared";
// Add this import from the index.ts file, where it contains the definition of the auth object.
import { auth } from '../..';

const fetchConnection = async (
	connections: ConnectionsManager,
	projectExternalId: string | undefined,
): Promise<PiecePropValueSchema<typeof auth>> => {
	if (isNil(projectExternalId)) {
		throw new Error('This project is missing an external id');
	}
	// the naming convention here is gelato_projectExternalId
	const connection = await connections.get(`gelato_${projectExternalId}`);
	if (isNil(connection)) {
		throw new Error(`Connection not found for project ${projectExternalId}`);
	}

	return connection as PiecePropValueSchema<typeof auth>;
};


export const newFlavorCreated = createTrigger({
   requireAuth: false,
   name: 'newFlavorCreated',
   displayName: 'new flavor created',
   description: 'triggers when a new icecream flavor is created.',
   props: {
      dropdown: Property.Dropdown({
         displayName: 'Dropdown',
         required: true,
         refreshers: [],
         options: async (_, {
            connections,
            project
         }) => {
            const connection = await fetchConnection(connections, (await project.externalId()));
            // your logic
            return {
               options: [{
                  label: 'test',
                  value: 'test'
               }]
            }
         }
      })
   },
   sampleData: {},
   type: TriggerStrategy.POLLING,
   async test({connections,project}) {
      const connection = await fetchConnection(connections, (await project.externalId()));
      // use the connection with your own logic
      return []
   },
   async onEnable({connections,project}) {
      const connection = await fetchConnection(connections, (await project.externalId()));
      // use the connection with your own logic
   },

   async onDisable({connections,project}) {
      const connection = await fetchConnection(connections, (await project.externalId()));
      // use the connection with your own logic
   },

   async run({connections,project}) {
    const connection = await fetchConnection(connections, (await project.externalId()));
      // use the connection with your own logic
      return []
   },
});
