gh api

gh api <endpoint> [flags]

Makes an authenticated HTTP request to the GitHub API and prints the response.

The endpoint argument should either be a path of a GitHub API v3 endpoint, or graphql to access the GitHub API v4.

Placeholder values {owner}, {repo}, and {branch} in the endpoint argument will get replaced with values from the repository of the current directory or the repository specified in the GH_REPO environment variable. Note that in some shells, for example PowerShell, you may need to enclose any value that contains {...} in quotes to prevent the shell from applying special meaning to curly braces.

The default HTTP request method is GET normally and POST if any parameters were added. Override the method with --method.

Pass one or more -f/--raw-field values in key=value format to add static string parameters to the request payload. To add non-string or placeholder-determined values, see -F/--field below. Note that adding request parameters will automatically switch the request method to POST. To send the parameters as a GET query string instead, use --method GET.

The -F/--field flag has magic type conversion based on the format of the value:

  • literal values true, false, null, and integer numbers get converted to appropriate JSON types;
  • placeholder values {owner}, {repo}, and {branch} get populated with values from the repository of the current directory;
  • if the value starts with @, the rest of the value is interpreted as a filename to read the value from. Pass - to read from standard input.

For GraphQL requests, all fields other than query and operationName are interpreted as GraphQL variables.

To pass nested parameters in the request payload, use key[subkey]=value syntax when declaring fields. To pass nested values as arrays, declare multiple fields with the syntax key[]=value1, key[]=value2. To pass an empty array, use key[] without a value.

To pass pre-constructed JSON or payloads in other formats, a request body may be read from file specified by --input. Use - to read from standard input. When passing the request body this way, any parameters specified via field flags are added to the query string of the endpoint URL.

In --paginate mode, all pages of results will sequentially be requested until there are no more pages of results. For GraphQL requests, this requires that the original query accepts an $endCursor: String variable and that it fetches the pageInfo{ hasNextPage, endCursor } set of fields from a collection. Each page is a separate JSON array or object. Pass --slurp to wrap all pages of JSON arrays or objects into an outer JSON array.

--silent
Do not print the response body
--slurp
