Yes, you can send many coins at once using the "Send with CSV" option in the Administrator's Coin section.
1) Simply click the "Send with CSV" button and download the CSV template.
2) Open the file and fill in all the columns. The Teacher email and Comment fields are optional. If the Teacher email is left empty, the coin will be sent from the uploading Administrator, otherwise it will be sent from the specified teacher.
3) Save your file as a CSV.
4) Upload your file. Once uploaded CritterCoin will display any errors due to missing or invalid data in the CSV.
5) If all your data is correct processing will begin. Depending on the size of your upload and the current queues on CritterCoin it may take several minutes or longer to complete. You will receive an email when it is complete. If there were any errors there will be a button in the email that will allow you to retry the errored coins.
NOTE: When sending in bulk using the CSV students will not receive iOS or Android message notifications or emails. However, if they are signed into their CritterCoin app, they will receive a real-time notification when they earn the coins.
