User Authentication

For Consumers:

Guests vs Logged in Customers

By default any user visiting a slerp powered site is a guest and slerp supports guest checkout so does not require account creation as part of the checkout process.

In many simple e-commerce setups a guest checkout will be more than sufficient, to determine if you want to offer account creation and login first decide:

• Do you want to offer a customer the option to quickly repeat previous orders? - This requires an account
• Do you want to allow customers to save data like their phone, email and address for easy completion of future orders? - This requires an account
• Do you want to collect data like birthdate on a customer? - This requires an account

If you would like to offer account creation this is how...

Creating and editing customer accounts

Creating an account:

To create an account you need to, at least, pass a name (first or last) an email and a password (+ confirmation):

Request:

mutation CreateCustomer($firstName: String!, $lastName: String!, $email: String!, $password: String!, $passwordConfirmation: String!, $merchantId: ID!, $contactNum: String!, $birthdate: String, $marketingOptIn: Boolean) {
    createCustomer(firstName: $firstName, lastName: $lastName, email: $email, password: $password, passwordConfirmation: $passwordConfirmation, merchantId: $merchantId, contactNum: $contactNum, birthdate: $birthdate, marketingOptIn: $marketingOptIn) {
      id
      firstName
      lastName
      email
      contactNum
      salutation
      apiKey
    }
  }

Example Variables:

{
  "email": "[email protected]",
  "firstName": "firstname",
  "lastName": "lastname",
  "birthdate": "2002-06-27", // Optional
  "contactNum": "+4407777777777", // Optional
  "password": "password", // must be at least 6 chars long
  "passwordConfirmation": "password",
  "marketingOptIn": true, // boolean, should be false unless user ticks
  "merchantId": "2ba090b2-d4dc-4fd1-ba5c-9e0b73586673" // ID of merchant
}

Success:

If successful you will receive a response which contains a customer ID and apiKey. These are things you may need later for customer specific API calls.

{
  "data": {
    "createCustomer": {
      "apiKey": "cus4921c3eeb488255775333fb49c0d0ef5",
      "contactNum": "+4407777777777",
      "email": "[email protected]",
      "firstName": "firstname",
      "id": "9807163c-3986-4c99-9d10-cf379e7c6b44",
      "lastName": "lastname",
      "salutation": null
    }
  }
}

Error:

{
  "data": {
    "createCustomer": null
  },
  "errors": [
    {
      "locations": [
        {
          "column": 0,
          "line": 2
        }
      ],
      "message": "Account already exists. Please sign in.",
      "path": [
        "createCustomer"
      ]
    }
  ]
}

Logging in a customer

Request:

query CustomerAuth($email: String!, $password: String!, $merchantId: ID!) {
  customerAuth(email: $email, password: $password, merchantId: $merchantId) {
    id
    firstName
    lastName
    salutation
    email
    apiKey
  }
}

Example Variables:

{
  "email": "[email protected]",
  "password": "password",
  "merchantId": "2ba090b2-d4dc-4fd1-ba5c-9e0b73586673"
}

Success:

{
  "data": {
    "customerAuth": {
      "apiKey": "cusa10a4267ab8a8981f005744a771c77a0",
      "email": "[email protected]",
      "firstName": "firstname",
      "id": "a01ae086-dc25-4ae3-851f-01a4c6edd915",
      "lastName": "lastname",
      "salutation": "Mr"
    }
  }
}

Error:

{
  "data": {
    "customerAuth": null
  },
  "errors": [
    {
      "locations": [
        {
          "column": 0,
          "line": 2
        }
      ],
      "message": "Wrong email or password",
      "path": [
        "customerAuth"
      ]
    }
  ]
}

Editing a customer profile:

mutation EditCustomer($customerId: ID!, $firstName: String!, $lastName: String!, $email: String!, $merchantId: ID!, $currentPassword: String, $password: String, $passwordConfirmation: String, $contactNum: String, $birthdate: String) {
  editCustomer(
    customerId: $customerId
    firstName: $firstName
    lastName: $lastName
    email: $email
    merchantId: $merchantId
    currentPassword: $currentPassword
    password: $password
    passwordConfirmation: $passwordConfirmation
    contactNum: $contactNum
    birthdate: $birthdate
  ) {
    id
    first_name
    last_name
    email
    contact_num
    birthdate
  }
}

example variables:

{
  "birthdate": null,
  "contactNum": "+447777777777",
  "customerId": "a01ae086-dc25-4ae3-851f-01a4c6edd915",
  "email": "[email protected]",
  "firstName": "firstname",
  "lastName": "lastname",
  "merchantId": "2ba090b2-d4dc-4fd1-ba5c-9e0b73586673"
}

Resetting a customer password

The easiest way to reset a user PW is to redirect them to https://${merchant.slug}.slerp.com/forget_password (or https://${merchant.slug}.slerp.com.integrations.slerp.io/forgotpassword if testing). This will then allow user to trigger a reset via their registered email.
