We are trying to use FB conversion API for better targeted ads. I was informed today that our Demandware subscription (Sales force commerce cloud) only allows 8 api calls per page load. This is not a problem when people browse, but at checkout we have 6 api calls going off already, and if we exceed 8 api calls the system (SFCC) crashes. Any ideas as to how to either structure it so the tag firing can be bundled into one call, or how we can store the data on the server side elsewhere, to be fired in increments over night?</p>\n"},{"tags":["python","discord","discord.py"],"answers":[{"owner":{"reputation":1,"user_id":16178423,"user_type":"registered","profile_image":"https://i.stack.imgur.com/hhYby.png?s=128&g=1","display_name":"i-am-cal","link":"https://stackoverflow.com/users/16178423/i-am-cal"},"is_accepted":false,"score":0,"last_activity_date":1623259320,"last_edit_date":1623259320,"creation_date":1623259222,"answer_id":67908917,"question_id":67908882,"content_license":"CC BY-SA 4.0"}],"owner":{"reputation":11,"user_id":15601103,"user_type":"registered","profile_image":"https://www.gravatar.com/avatar/b419e9b18f3522f2ee9d002932ba7198?s=128&d=identicon&r=PG&f=1","display_name":"Deyan Nikolov","link":"https://stackoverflow.com/users/15601103/deyan-nikolov"},"is_answered":false,"view_count":7,"answer_count":1,"score":0,"last_activity_date":1623259320,"creation_date":1623259067,"question_id":67908882,"share_link":"https://stackoverflow.com/q/67908882","body_markdown":"Okay, I know that the title isn't very descriptive, but please hear me out.\r\n\r\nI'm trying to create a help "log" command:\r\n\r\n```\r\n@client.command()\r\nasync def logs(ctx):\r\n for channel in ctx.guild.channels:\r\n if channel.name == "henry-logs":\r\n await ctx.send("Henry Logs channel is already setup.

I followed all necessary steps as given in this blog: [https://www.survivingwithandroid.com/cloud-iot-core-esp32/?unapproved=16731&moderation-hash=eeb8406949900a6f926ac15fdb54c7b6#comment-16731] --My code is the same as given here, just the WiFi SSID and other details are different.\r\nI also referred to these blogs:\r\n2. [https://ludovic-emo.medium.com/how-to-send-esp32-telemetry-to-google-cloud-iot-core-caf1a952020d]\r\n3. [https://medium.com/@gguuss/accessing-cloud-iot-core-from-arduino-838c2138cf2b]\r\n4. I also started a course on LinkedIn learning called "Learning Cloud IoT Core" by Lee Assam.\r\n\r\nBut I kept getting this message on the serial monitor:\r\n```\r\nSettings incorrect or missing a cyper for SSL\r\nConnect with mqtt.2030.ltsapis.goog:8883\r\n```\r\n\r\nI'm certain that the device ID and every other detail is correct. I suppose the root certificate is wrong. I tried several methods to generate the root certificate, the most common one being the last certificate we get from after executing this command:\r\n```openssl s_client -showcerts -connect mqtt.2030.ltsapis.goog:8883```\r\n\r\nI also tried using any of the root certificate bytes for the certificates with Google Trust Services (GTS) as the certificate authority (CA). Using this command:\r\n```curl pki.goog/roots.pem``` But that document has so many root certificates! Which one do I choose?\r\n\r\nI'm also not able to specify a binary root cert static as given here: https://github.com/Nilhcem/esp32-cloud-iot-core-k8s/blob/master/02-esp32_bme280_ciotc_arduino/ciotc_config.h\r\n\r\nHowever, they all give the same message on the serial monitor. So my questions are:\r\n1. Where am I going wrong?\r\n2. How to generate root certificate?\r\n3. How to specify a binary root cert static ?\r\n4. The example universal-lwmqtt form Google Cloud IoT Core JWT library specifies 2 root certificates, primary and backup. How to obtain those? [https://github.com/GoogleCloudPlatform/google-cloud-iot-arduino/blob/master/examples/universal-lwmqtt/ciotc_config.h]\r\n\r\nI have noticed that there were many others who had faced the exact same problem, however it was never resolved.
