=head1 NAME
Bugzilla::API::1_0::Resource - The Web Service Resource interface to Bugzilla
=head1 DESCRIPTION
This is the standard API for external programs that want to interact
with Bugzilla. It provides endpoints or methods in various modules.
You can interact with this API via L<REST|Bugzilla::API::1_0::Server>.
=head1 CALLING METHODS
Methods are grouped into "packages", like C<Bug> for
L<Bugzilla::API::1_0::Resource::Bug>. So, for example,
L<Bugzilla::API::1_0::Resource::Bug/get>, is called as C<Bug.get>.
For REST, the "package" is more determined by the path used to access the
resource. See each relevant method for specific details on how to access via REST.
=head1 USAGE
Full documentation on how to use the Bugzilla API can be found at
L<https://bugzilla.readthedocs.org/en/latest/api/index.html>.
=head1 ERRORS
If a particular API call fails, it will throw an error in the appropriate format
providing at least a numeric error code and descriptive text for the error.
The various errors that functions can throw are specified by the
documentation of those functions.
Each error that Bugzilla can throw has a specific numeric code that will
not change between versions of Bugzilla. If your code needs to know what
error Bugzilla threw, use the numeric code. Don't try to parse the
description, because that may change from version to version of Bugzilla.
Note that if you display the error to the user in an HTML program, make
sure that you properly escape the error, as it will not be HTML-escaped.
=head2 Transient vs. Fatal Errors
If the error code is a number greater than 0, the error is considered
"transient," which means that it was an error made by the user, not
some problem with Bugzilla itself.
If the error code is a number less than 0, the error is "fatal," which
means that it's some error in Bugzilla itself that probably requires
administrative attention.
Negative numbers and positive numbers don't overlap. That is, if there's
an error 302, there won't be an error -302.
=head2 Unknown Errors
Sometimes a function will throw an error that doesn't have a specific
error code. In this case, the code will be C<-32000> if it's a "fatal"
error, and C<32000> if it's a "transient" error.
