Database APIs

Overview

GraphQL always uses the POST method and the same endpoint to make requests. Here, we are going to imagine we have a products table under a project, and we are going to create, read, update, and delete a product from this table using GraphQL.

The endpoint URL is as follows:

https://YOUR_PROJECT_ID.api.deskree.com/api/v1/graphql

You can access the GraphQL schema for your project in:

• API Docs web viewer

• Downloading from the API Docs page

Note that the Users table is a special table and does not allow Creation or Deletion directly via GraphQL requests since account creation/removal is handled by AUTH APIs. For more information, view our Users Table guide.

Query

The body query to get a list of products, including all of the objects' properties is as follows:

query products {
    products {
        uid
        name
        price
        author
        updatedAt
        createdAt
    }
}

And the body response to the request above is:

{
    "data": {
        "products": [
            {
                "uid": "0ynOfuBeph76aqH6MkBc",
                "name": "Resee's",
                "price": 0.99,
                "author": "",
                "updatedAt": "2022-07-04T16:01:09-04:00",
                "createdAt": "2022-06-29T11:50:43-04:00"
            },
            {
                "uid": "224oR81doLNtQzfDsGxy",
                "name": "KitKat",
                "price": 1.49,
                "author": "",
                "updatedAt": "2022-06-28T16:53:29-04:00",
                "createdAt": "2022-06-28T16:53:29-04:00"
            }
        ]
    }
}

The beauty of GraphQL is that you can fetch only the necessary information just by changing the query structure. Here's another example of how to fetch a single product by UID, and this time let's just fetch the name and price properties of it:

query products {
    products (uid: "0ynOfuBeph76aqH6MkBc") {
        name
        price
    }
}

And the result for this new request is:

{
    "data": {
        "products": [
            {
                "name": "string",
                "price": null
            }
        ]
    }
}

Create Mutation

Now, let's create a product, and return this product's uid, name, and price. To do so, we can have a body mutation as follows:

mutation createProduct {
    createProduct (data: { name: "Kopenhagen", price: 1.00 }) {
        uid
        name
        price
    }
}

And the result of our request is:

{
    "data": {
        "createProduct": {
            "uid": "0ynOfuBeph76aqH6MkBc",
            "name": "Kopenhagen",
            "price": 1
        }
    }
}

Update Mutation

Now, let's update the previous product price, and return the product's uid, name, and price. To modify a product, we need to specify which product to update, and the new value we want to set. To do so, we can have a body mutation as follows:

mutation updateProduct {
    updateProduct("uid": "0ynOfuBeph76aqH6MkBc", data: { price: 3.50 }) {
        uid
        name
        price
    }
}

And the result of our request is:

{
    "data": {
        "createProduct": {
            "uid": "0ynOfuBeph76aqH6MkBc",
            "name": "Kopenhagen",
            "price": 3.50
        }
    }
}

Delete Mutation

To delete a product, we just need to specify the uid of the object within the following mutation:

mutation deleteProduct {
    deleteProduct (uid: "0ynOfuBeph76aqH6MkBc")
}

And your body response will be:

{
    "data": {
        "deleteProduct": "Document Deleted"
    }
}
