# Multi Dimensional Config
> Learn how to configure GraphQL Multi-Dimensional Credential
## Overview
GraphQL Multi-Dimensional Credential allows you to fetch user data via GraphQL APIs and validate eligibility across multiple dimensions. used to retrieve data for the extent of user participation.
If you want to understand the workflow and considerations of GraphQL credentials, please refer to the [introduction](/quest/credential-api/graphql-cred/introduction)
***
## Config process
### 1. Finding the Config in Task Settings
The option to configure GraphQL credential can be found in step 3, `Task Settings` of quest creation on the Galxe Dashboard, under the `Import Your Own Data` task type.
### 2. Basic Config
* **ID Type**
`ID Type` provides various identity options, including social accounts, blockchain addresses, and other unique identifiers.
* **Title**
Give your credential an enticing title.
* **Credential Source**
Choose `GraphQL` type
* **Type**
Choose `Multi Dimension`
### 3. Specify Dimensions
In Multi-Dimensional Credential configuration, you need to define specific dimensions to ensure each dimension is clearly identified and usable.
* **Identifier**:
* Enter a unique identifier for the dimension, e.g., `mainnet_eth_balance`.
* The identifier is used for internal calls and logic operations, and it must be globally unique.
* **Display Name**:
* Enter a display name for the dimension, e.g., `ETH balance on Mainnet`.
* This name will be displayed in the UI for user understanding.
* **Type**:
* Select the dimension type `COUNTER` from the dropdown menu.
* **Description**:
* Enter a description to explain the purpose of the dimension, e.g., "This dimension tracks the ETH balance of a user on Mainnet".
* The description must be within 256 characters.
### 4. Configure API
* Input Endpoint Example:
```plaintext theme={null}
https://api.example.com/query
```
* Add Headers (Optional)
```json theme={null}
`access-token`: `YOUR_TOKEN`
```
* Input Query:
```graphql theme={null}
query info($address: String!) {
tokenBalance(address: $address) {
balance
}
}
```
### 5. Test API Response
* **Input a test address and send the request to confirm the response**:
```json theme={null}
{
"balance": 100
}
```
### 6. Write Expressions
* **Token Balance Output**:
```javascript theme={null}
function(resp) {
return {
"mainnet_eth_balance": resp.balance
};
}
```
### 7. Description
Description of the certificate, supports rich text input, maximum 200 characters.
### 8. Call-to-Action Link
Guide users to specific operation pages to complete interactive tasks.
### 9. Participation End Time && Update Frequency (Optional)
* **Participation End Time**:
Control the time range of the credential, prohibiting new validations after the deadline.
* **Update Frequency**:
Remind users of the frequency of API data source updates, such as once a day or once every two days.
### 10. Config Rule
Configure rules in Quest to determine whether users meet the criteria.
* **Threshold Evaluation**:
When a certain threshold condition is met (e.g., >0), assign a fixed points directly.
* **Multiple Entries(Optional)**:
Enable users to claim rewards repeatedly once certain credentials are fulfilled, for example, a user earns 10 points for each 1 ETH they hold. If the user holds 5 ETH, they will earn 50 points.

## Example
### Galxe MSU Space points balance
* **Specify Dimensions**
Identifier:`points_balance`
Display Name:`points balance on msu`
Type:`COUNTER`

* **Endpoint**
```plaintext theme={null}
https://graphigo-business.prd.galaxy.eco/query
```
* **Headers**
`No header`
* **Query**
```graphql theme={null}
query info($address: String!) {
space(id: 68267) {
addressLoyaltyPoints(address: $address) {
points
}
}
}
```
* **Response**
```json theme={null}
{
"space": {
"addressLoyaltyPoints": {
"points": 100
}
}
}
```
* **Expression**
```javascript theme={null}
function(resp) {
try {
let points = BigInt(resp.space.addressLoyaltyPoints.points);
return { "points_balance": points };
} catch (error) {
return { "points_balance": 0 };
}
}
```
