Probably bug in dynamic notifications

Mon, 05 Jan 2026 17:57:16 +0000

I use the iOS app „cache notifier“ which works quite nice. Now I am on holiday and I get notifications from home.

It seems like PGC inserts my home coordinates. cache notifier shows the correct coordinates. If I the. turn off cache notifier and turn it on again, PGC shows the correct coordinates.

Better Documentation of Dynamic Location Update URL

Mon, 18 Aug 2025 07:31:03 +0000

The New Cache Notifiers page has documentation for setting up GPS Logger for Android, but it does not have a generic documentation of the parameters supported by the https://project-gc.com/api/UserLocation/Update/ API.

A documentation would be nice, especially for parameters that are non-obvious, e.g. like this:

# Help: Dynamic Notifiers

You can dynamically update some settings of a notifier by using the URL https://project-gc.com/api/UserLocation/Update/ with parameters. Supported parameters are:

protocol=1 - the update protocol to use, this must always be 1
uid=<USER-ID> - your user ID. Use the user id from your settings page.
token=<TOKEN> - the access token to Project GC. Use the token from your settings page. Keep in mind that the token should be kept as safe as a password.
nid=<NOTIFIER-ID> - the ID of the notifier. You can see a notifier's ID if you edit it
ts=<timestamp> - the timestamp of your update, in ISO-format, e.g. 2025-01-31T14:35:59+0100. Updates that have a timestamp that is older than the most recent update are ignored (?)
latitude=<latitude> - the latitude of the dynamic location, using decimal degrees, such as 12.34567
longitude=<longitude> - the latitude of the dynamic location, using decimal degrees, such as 56.78901
acc=<accuracy> - the accuracy of your latitude/longitude measurement in meters. (why would this be relevant?)
enable=1 - if you add this parameter and the notifier is currently disabled, the update will enable it

To update a notifier, add the parameters to the URL after a question mark, separate them via & signs, for example like this: https://project-gc.com/api/UserLocation/Update/?protocol=1&uid=<USER-ID>&latitude=<latitude>&longitude=<longitude>&ts=<timestamp>&token=<TOKEN>&nid=<NOTIFIER-ID>

New cache notifier dynamic location updater

Mon, 10 Jun 2024 20:31:04 +0000

This is not a question, but rather a solution created by me to ease the process of updating dynamic location for new cache notifiers.

I found the configuration of GPS logger overwhelming for what it's supposed to do regarding the new cache notifiers at Project-GC.

I have created a simple yet useful webapp that imitate the request that GPS logger makes to update the new cache notifier with dynamic location. It does not use any data on server side. It just composes a URL that GPS logger sends on location updates and performs it on behalf of the user. It remembers the values in user's browser.

One can choose location from the map or use the device's GPS to update the notifier location. It should work on all mobile devices.

If you want, you can check it out working here: https://fracz.github.io/pgc-location-updater/ and the source code is available here: https://github.com/fracz/pgc-location-updater/blob/main/index.html

Happy hunting!

Sharing Dynamic Location for someone else?

Fri, 09 Jun 2023 06:22:25 +0000

I use the Dynamic Location for New Cache Notifiers. Sometimes I travel and hike alone. Can I share my location with someone else? Just a map with my current location or history via a special link. That would be a cool feature!

My Dynamic html link doesn't work, all other links that take me to different sites do, I use a mac, any recommendations?

Tue, 22 Dec 2015 03:19:04 +0000

I use a mac, and when I put the Dynamic link HTML in my edit profile section the tables show up on my profile, when I click the table, I am asked if I want to navigate to the Gproject GC site, when I select yes, nothing happens. All other links I have work just fine that take me away from my geocaching profile, but this one does not. Any suggestions?

Specific Tab Dynamic Image

Wed, 24 Sep 2014 16:14:46 +0000

Is there a way, or can a feature be added to pull a dynamic image by tab? I would like to display the Hides tab as an image on my geocaching profile.
