The notification you built reads for your calendar says “{{Title}} starts {{Starts}}.” The word “starts” is fixed text, and the two pieces in double curly brackets are dynamic Ingredients. Each time the Applet runs, IFTTT swaps them for the real event’s title and start time.
Next to a text field, you’ll find an Add ingredient button. Select it, and the Trigger offers a list of what it can hand over. For the calendar Trigger, that includes the event’s title, description, location, start and end times, and video call link. Choose one to add it to the field.
More isn’t always better. The Spotify Action in Chapter 2 came with both Title and Url in its search query. In this case, only using the song's title made sense because that is what you want to search.
When an Applet’s message looks wrong, the Ingredients are often the first place to check. The next chapter covers that and more.
