Send fax with OVH API from Google Script. Error: [recipients] phoneNumber Data is not a

Bonjour à la communauté,

Je souhaite appeler l'API OVH depuis un google script. Cette dernière version fonctionne en 'GET' et en 'POST'. Je n'ai enfin plus de "Invalid signature". J'ai trouvé comment passer les paramètres BODY. Mais j'ai maintenant une dernière erreur que je n'arrive pas à passer : "[recipients] phoneNumber Data is not an array for an array type".

Pourtant le recipients semble bien être un array :

`$body = 'pdfUrl="http://www.africau.edu/images/default/sample.pdf"&recipients=[ "0033972152245" ]'`

Mon google script est ci-dessous.

function ovh_api() {

/** to be changed by your account data */
$billingAccount= 'saxxxxxxx-ovh-1' //has to finised by '-ovh-1' or '-ovh-2' or '-ovh-3'...
$serviceName= '00339xxxxxxxx' //your fax number

/** "documentation" is here:
https://api.ovh.com/console/#/telephony/%7BbillingAccount%7D/fax/%7BserviceName%7D/settings/sendFax#POST
*/
$url = 'https://eu.api.ovh.com/1.0/telephony/'+$billingAccount+'/fax/'+$serviceName+'/settings/sendFax'
$method = 'POST'
$body = 'pdfUrl="http://www.africau.edu/images/default/sample.pdf"&recipients=[ "0033972152245" ]'

/** All those $body failed with same message "phoneNumber Data is not an array for an array type"
$body='pdfUrl="http://www.africau.edu/images/default/sample.pdf"&recipients=%5B0033972152245%5D'
$body = 'pdfUrl="http://www.africau.edu/images/default/sample.pdf"&recipients=[ "+33972152245" ]'
