I am getting the following result when I run the script:
{"success":false,"errors":[{"code":7003,"message":"Could not route to \/zones\/dns_records, perhaps your object identifier is invalid?"},{"code":7000,"message":"No route for that URI"}],"messages":[],"result":null}I am attempting to update and A record of a subdomain on an account with multiple domains. Is anyone else getting this error?
I have the same issue, also in an account with multiple domains. No solution on this thread worked so far.
Thank you for the script saved me lots of time. Tweaked to add DNS Record instead of updating. I did not add a check to see if the record already exist.

just a heads up everyone, apparently Cloudflare made a few changes to their API and I found out the hards way today (bit of a downtime). All you need to do is to add a space character ( ) in every regex when parsing a field.
specifically:
if [[ $record == *"\"count\":0"* ]]; then
needs to become
if [[ $record == *"\"count\": 0"* ]]; then
old_ip=$(echo "$record" | grep -Po '(?<="content":")[^"]*' | head -1)
to
old_ip=$(echo "$record" | grep -Po '(?<="content": ")[^"]*' | head -1)
*"\"success\":false"*)
has to become
*"\"success\": false"*)
Thanks @mrwhizzy
I also update my sed sample here.

Updated my scripts but still doesn't seem to work.
Anyone got it working again?
grep -Po '(?<="id":")[^"]*')
change to
grep -Po '(?<="id": ")[^"]*')
Why Cloudflare why do you do these things.
Thanks for the update
tx guys for the update, was wondering what was going on !
Did they change something again? Scripts no longer seem to work..
@niklasmato, yes they did, I've uploaded an up-to-date version of the script on GitHub which will work a bit more reliably no matter if they have spaces after semicolons or not, plus it will also update multiple records.

change -H "X-Auth-Email: $auth_email" -H "X-Auth-Key: $auth_key" to -H "Authorization: Bearer $auth_key"
and
change use sed to instead of grep to parse json data
like
sed -E "s/.+\{\"id\":\"([a-f0-9]+)\".+\"type\":\"A\".+/\1/g"
and
if [ -f $id_file ] && [ -n $(sed -n '1p' $id_file) ] && [ -n $(sed -n '2p' $id_file) ]; then

Hi all,
Previously I have posted a bash/systemd version fork of this script in another gist, I have moved and updated the script to an actual repository, please kindly visit it instead at: https://github.com/lifehome/systemd-cfddns
Regards,
Ivan
I had to change the "update" line to remove the quotes around "$proxied". Cloudflare expects that json value to be a boolean:
update=$(curl -s -X PUT "https://api.cloudflare.com/client/v4/zones/$zone_identifier/dns_records/$record_identifier" -H "Authorization: Bearer $api_token" -H "Content-Type: application/json" --data "{\"id\":\"$zone_identifier\",\"type\":\"A\",\"proxied\":$proxied,\"name\":\"$record_name\",\"content\":\"$ip\"}")
