Extracting Salesforce Id from a Lightning URL in an Apex REST endpoint

Question

Creating an Apex REST endpoint to receive updates for Opportunities. The caller of the endpoint will send the full Lightning URL for an Opportunity. For example: https://example.lightning.force.com/lightning/r/0061U00000Gs7RqQAJ/view.

In a report of Opportunities with their Ids, it looks like there are 3 extra chars on the end of the ID in the URL. For example, the above Opportunity has an Id of 0061U00000Gs7Rq rather than 0061U00000Gs7RqQAJ. I need the Id to populate a Lookup(Opportunity) field in an SObject.

Here's the code I'm using to extract the ID from a URL...

  private static ID getSalesforceId(String url) {
    Pattern urlPattern = Pattern.compile('.*/lightning/r/([a-zA-Z0-9]{15,18})/.*');
    Matcher urlMatcher = urlPattern.matcher(url);
    ID opportunityId;
    if (urlMatcher.matches()) {
      opportunityId = (ID) urlMatcher.group(1);
    }
    return opportunityId;
  }

Questions

Is there an existing method I can call to extract the Id?
If not, should I clip the last three characters of the Id portion of the URL passed to me or can I use that longer Id to set the value of a Lookup(Opportunity) field?

Additional information: What are Salesforce ID's composed of. — sfdcfox, Mar 09 '21 at 17:13

The longer id is a Case Insensitive version of the other one.

They are equivalent in all circumstances (other than string comparisons)

You can convert the Id if you like, like this:

String shortId = String.valueOf(longId).substring(0, 15);

But there is no need - what you have will work fine.
