Troubleshooting

General Troubleshooting

The best thing you can do when troubleshooting problems with your notification is to use the apprise object itself from the command line and add up the verbosity of the command (the more v's you specify, the more verbose it gets):

# In the below example, I am trying to figure out why my mailto:// line
# isn't working:
python apprise -vvv -t "test title" -b "test body" \
    mailto://user:[email protected]

The output can help you pinpoint what is wrong with your URL.

If the output appears cryptic, or you feel that you've exhausted all avenues, Don't be afraid to open a ticket and ask here. It greatly helps if you share the output received from your debug response. It might be just a simple tweak to your URL that is needed, otherwise we might have a good bug we need to solve.

Just be cautious as the debugging information can potentially expose personal information (such as your password and/or private access tokens) to the screen. Please remember to erase this or swap it with some random characters before posting such a thing publicly.

Special Characters and URL Conflicts

Apprise is built around URLs. Unfortunately URLs have pre-reserved characters it uses as delimiters that help distinguish one argument/setting from another.

For example, in a URL, the &, /, and % all have extremely different meanings and if they also reside in your password or user-name, they can cause quite a troubleshooting mess as to why your notifications aren't working.

Now there is a workaround: you can replace these characters with special %XX character-set (encoded) values. These encoded characters won't cause the URL to be mis-interpreted allowing you to send notifications at will.

Below is a chart of special characters and the value you should set them:

Character	Escape Code	Description
%	%25	The percent sign itself is the starting value for defining the %XX character sets.
&	%26	The ampersand sign is how a URL knows to stop reading the current variable and move onto the next. If this existed within a password or username, it would only read 'up' to this character. You'll need to escape it if you make use of it.
(a space)	%20	While most URLs will work with the space, it's a good idea to escape it so that it can be clearly read from the URL.
/	%2F	The slash is the most commonly used delimiter that exists in a URL and helps define a path and/or location.
@	%40	The at symbol is what divides the user and/or password from hostname in a URL. if your username and/or password contains an '@' symbol, it can cause the url parser to get confused.
+	%2B	By default a addition/plus symbol (+) is interpreted as a space when specified in the URL. It must be escaped if you actually want the character to be represented as a +.
,	%2C	A comma only needs to be escaped in extremely rare circumstances where one exists at the very end of a specific URL that has been chained with others using a comma. See PR#104 for more details as to why you may need this.
:	%3A	A colon will never need to be escaped unless it is found as part of a user/pass combination. Hence in a url http://user:pass@host you can see that a colon is already used to separate the username from the password. Thus if your {user} actually has a colon in it, it can confuse the parser into treating what follows as a password (and not the remaining of your username). This is a very rare case as most systems don't allow a colon in a username field.
