Hey @Kamlesh_Singh

Yes, you can achieve that in 1 API call by developing a custom API in any of the content type collection controller.

Below is an example on how to achieve that:

In /api/content-type/routes/content-type.js file:

{
    method: 'POST',
    path: '/your-api-name',
    handler: 'api::collectionName.collectionName.fetchAllData',
}

and add the function inside /api/content-type/controllers/content-type.js file:

fetchAllData(): async (ctx) => {

    const collection1 = await strapi.db.query('api::collection-1.collection-1').findMany();
    
    const collection2 = await strapi.db.query('api::collection-2.collection-2').findMany();

    ctx.send({
      status: 200,
      data: {
        'collection1_data': collection1,
        'collection2_data': collection2 
      }
    })
}

Set permission of the custom API from roles and you are good to go for executing the custom api.

Hope this information helps you :slight_smile:
