How to define query or mutation in 8base and call it just by it's name in front end

Hi, i wanted to know if it is possible to define my query or mutation with its parameters in 8base and just call it from outside and use it


Your question is abstract. Please, could you describe your case, preferably with some examples?

what i mean is, is it possible to define a query or mutation like this:

in 8 base and then just call “createUser” and put it’s parameters from front end, all this just by calling this mutation “createUser”

Thank you for the update!

Api explorer is mainly used for testing various requests. In order to use GQL requests in another application you can check this page of docs:

If on the client application you use some kind of framework you should check what tools are there for working with GQL and your framework. For example you can check the most popular tool for react here:

Hello again!

How to create your custom function and upload it to your project you can see at this example:

  1. First of all, you need to create a local project on your computer:

     * You need to install 8base packets on you computer:
     #Install 8base globally
     npm install -g 8base-cli
     *After that, you need to login:
     #Login with CLI
     8base login
     *Chose the directory and point out the way to it:
     cd name_of_the_folder
     *The next step'll be init your project:
     #Init new 8base project
     8base init project_name
  2. Add your custom resolver

     import { FunctionContext, FunctionEvent, FunctionResult } from '8base-cli-types';
     import gql from 'graphql-tag';
     type EventData = {
       email: string;
       firstName: string;
       lastName: string;
     type ResultData = {
       success: boolean;
     // System mutation to create user
     const CREATE_USER = gql`
       mutation CreateUser($data: UserCreateInput!) {
         userCreate(data: $data) {
     export default async (
       event: FunctionEvent<EventData>,
       ctx: FunctionContext,
     ): FunctionResult<ResultData> => {
       const { email, firstName, lastName } =;
       // You also can make any other actions
       await ctx.api.gqlRequest(CREATE_USER, {
         data: {
       return {
         data: {
           success: true,
     extend type Mutation {
       customMutation(email: String!, firstName: String!, lastName: String!): SuccessResponse

After that register this resolver in 8base.yml in functions section

    type: resolver
      code: src/customMutation/handler.ts
    schema: src/customMutation/mutationSchema.graphql
  1. Deploy your project

8base deploy

  1. After that you can run your custom mutation from frontend

     const query = {
       query: `mutation {
           emial: "${email}"
           firstName: ${firstName}
           lastName: ${population}
         ) { 
     await fetch("", {
       method: "POST",
       headers: {
         "Content-Type": "application/json",
         Authorization: `Bearer ${idToken}`,
       body: JSON.stringify(query),
