[Anshuman200]

This file sets up a custom domain configuration for Solid App Maker, including DNS records for TXT and CNAME types.

Description

<-- short description of the template(s) and/or reason for update -->

Type of change

Please mark options that are relevant.

• New template
• Bug fix (non-breaking change which fixes an issue in the template)
• New feature (non-breaking change which adds functionality to the template)
• Breaking change (fix or feature that would cause existing template behavior to be not backward compatible)

How Has This Been Tested?

Please mark the following checks done

• Schema validated using JSON Schema template.schema
• Template functionality checked using Online Editor
• Template is checked using template linter
• Template file name follows the pattern <providerId>.<serviceId>.json
• resource URL provided with logoUrl is actually served by a webserver

Checklist of common problems

Mark all the checkboxes after conducting the check. Comment on any point which is not fulfilled.

• digital signatures are used and syncPubKeyDomain specified (yes, warnPhishing is an option, but some providers reject such templates by policy, so signing shall be a default)
• syncRedirectDomain is specified when intended to use redirect_uri parameter in the synchronous flow
• no TXT record with SPF content (i.e. "v=spf1 ...") instead of using SPFM record type on APEX
• txtConflictMatchingMode is set on TXT records which shall be unique on a label (like DMARC)
• variables are set to the smallest scope needed (i.e. limit possibility to be misused to set any arbitrary record and conflict with other template). Too broad scope example: @ TXT "%verification%". Better usage: @ TXT "foo-verification=%verification%".
• no variables as a host name to apply template on subdomain instead of standard host parameter
• no explicit usage of %host% variable in host attribute
• essential setting is used on records, which the user shall be able to change or remove manually later without dropping the whole template (like DMARC)

Example variable values

<-- to make review process easier please provide the whole testData object from the Online Editor after testing and using "Add as test" button. Hint: test also with "host" variable set. -->

There are fair number of issues in the template. Instead of going through each issue one by one could you consider something like the following instead.

{
  "providerId": "solidappmaker.in",
  "providerName": "Solid App Maker",
  "serviceId": "custom_domain",
  "serviceName": "Custom Domain Setup",
  "version": 1,
  "description": "Automatically connects your GoDaddy domain to SolidAppMaker.",
  "syncPubKeyDomain": "dckeys.solidappmaker.in",
  "records": [
    {
      "type": "TXT",
      "host": "%txt_name%",
      "ttl": "3600",
      "data": "%txt_value%"
    },
    {
      "type": "CNAME",
      "host": "%dcv_name%",
      "pointsTo": "%dcv_value%",
      "ttl": "3600"
    },
    {
      "type": "CNAME",
      "host": "%cname_name%",
      "pointsTo": "origin.solidappmaker.in",
      "ttl": "3600"
    }
  ]
}
