Syncing Tide Data to a Garmin Instinct Watch

We aren’t just business here on the blog. We often work on other projects for fun and to keep our programming skills tight. This one is to help us predict the best time to go surfing.

If anybody has the standard Garmin Instinct watch and wants Tide information on their watch is out of luck since Garmin wants you to spend twice as much to buy the fancy expensive Surf edition watch.

There is kinda a workaround by importing data into a Google Calendar with data from NOAA that will schedule events for the predicted tides. So, I decided to write a .NET Core app that goes out to NOAA and pulls back tide predictions, for a station ID that you specify, and a date range to get the predictions. It will then write that information to a CSV file that you can upload to a google map and then sync to your watch.

The .NET Core app will run on most any machine that has .NET Core installed (Windows, Mac, Linux). It will allow you to pass parameters for beginDate, endDate, station ID (from NOAA) and a filename to output the CSV to. What I did is just run it from 1/1/2021 through 12/31/2021 so that I can populate data for the entire year.

You can get my code on Github here: dafoink/tidesToGoogleAPI (github.com)

You can find out a NOAA stationID closest to you by going here: CO-OPS Map – NOAA Tides & Currents

Example, I live on Cape Hatteras, NC. My Station ID is 8654467


Sending Information to Catalina Support

There are times that you might have questions or problems when developing using an API. You contact support and they will ask you to send you the “payload” you are using when communicating with the Catalina API for Dynamics SL. The easiest way to do this, if you are using Postman as your testing environment, is to export the code. This is done in these simple steps

Step 1:
Got to your postman tab you are making the API call from and click on the “Code” link on the right of the screen

Step 2:
On the popup, click on cURL and then copy the text provided, paste it into an email, and send to Support.


Call Stored Procedures Using Catalina’s API for Dynamics SL and Postman

It is simple to call a stored procedure through a RESTful API call if you have Catalina’s API for Dynamics SL. You can call any stored procedure and pass parameters and retrieve data.

This is a demo on how to call a stored procedure using Postman and Catalina’s API for Dynamics SL.

First, to do this demo, you need to download and install Postman. Postman is a developer tool that allows you to interact with API’s easily so that you can test API calls to see how you call them and what data is returned. You can get Postman here: https://www.postman.com/

In the demo, we are going to call the stored procedure SOHeader_all. This stored procedure retrieves all Sales Order Headers (SOHeader) for a particular CpnyID and OrdNbr. NOTE: this is just an example. With Catalina’s API, you can call any stored procedure.

SOHeader_all has 2 parameters:
– @parm1: This parameter is for the CpnyID
– @parm2: This parameter is for the OrdNbr (can use a wildcard like ‘O000%’ which will bring back all orders that start with O000.

You can see what the procedure looks like here:

PROCEDURE [dbo].[SOHeader_all]
	@parm1 varchar( 10 ),
	@parm2 varchar( 15 )
AS
	SELECT *
	FROM SOHeader
	WHERE CpnyID = @parm1
	   AND OrdNbr LIKE @parm2
	ORDER BY CpnyID,
	   OrdNbr DESC

So, if you wanted to retrieve all orders that started with “O000” for CpnyID = “0060” you would call the stored procedure like this:

exec SOHeader_all @parm1='0060', @parm2='O000%'

So, now how to call this using Postman through Catalina’s API for SL?

First you need to know where your Catalina API is installed. I am going to use the server name yourserver.com as the domain name. So, for this example, we would look at the endpoint as the following:

http://yourserver.com/ctDynamicsSL/api/customSQL/<ProcedureName>

As you can see above, you would replace yourServer.com with wherever your server is. And you can see <ProcedureName> in the URL. this would be replaced with the actual stored procedure name you want to call (in this example, we are going to replace it with SOHeader_all). So, the new URL for the endpoint would look like the following:

http://yourserver.com/ctDynamicsSL/api/customSQL/SOHeader_all

In Postman, you would make it look like below. NOTE: when calling a customSQL stored procedure, you must use the action type of “POST”

Next, you need to set the authentication. This is done on the “Authorization” tab. Catalina’s API uses “Basic Auth”. So, make sure that you set the type for “Basic Auth” in the dropdown. And then enter the username and password that was given to you from your installer.

After that, you will have been given a SiteID from your installer. You will need to create a Header for that SiteID. You do this on the headers tab. You should enter that SiteID (in my example it is “DEFAULT”, but you would use the SiteID given to you by your installer) and the default CpnyID (in my example that is “0060”, but you would use your CpnyID of your database)

Finally, you will want to enter the body of the parameters that are being passed. There are 2 parameters for SOHeader_all (@parm1 and @parm2). The format of the body that you would set is below.

{
    "parameters": [
        {
            "name": "parm1",
            "value": "0060"
        },
        {
            "name": "parm2",
            "value": "O0005121"
        }
    ]
}

So, your Body tab in Postman would look like this (NOTE: make sure you select the “raw” radio button as shown below)

Then all you have to do is simply hit the “Send” button and the system should retrieve the results from your stored procedure call. In my example, it looks like below


Create a Contact Free Payment Solution for Dynamics SL (Mobile App)

This is a demo that shows you how to create a mobile app to interact with Dynamics SL to provide a “Contact Free” payment solution to help protect your employees and customers during COVID 19. The intended user of this example app would be a customer service rep, sales person, or field service rep who needs to collect payment from a customer (handy for collecting a deposit or down payment before delivery, installation, or service work to be done).

This demo uses Catalina’s API to search customers in SL and then lets the user to request a payment from a customer by generating a link and emailing it to the chosen customer. That customer then can click on the link and pay the amount which automatically creates a payment in SL’s AR.

NOTE: Source code for the mobile app can be found on Github here: https://github.com/CatalinaTechnology/SL-Mobile/tree/main/ctPayment

Check out the video of the demo on our Youtube channel here:

Below is a screenshot of the Android app from the above demo. First you can search for a customer by a keyword. That search will then bring back a list of results. You can then click on the customer you want to request funds for. The app will automatically fill in the email address of the customer (from the Customer record in Dynamics SL). You can change the email address if you want. You then enter a requested payment amount and hit submit. Once you do this, Catalina’s SLQuickCollect will send off an email to the customer with a link which will then allow them to make a PCI compliant secure payment. Once authorization occurs, SLQuickCollect will then create a payment in Dynamics SL automatically.

As mentioned below, if you want to have starter code on creating an Android App (with Visual Studio and Xamarin), you can check out an example on our Github here (NOTE: I would only consider this a starter. This is in no means something finished but enough to get you started)
