Curl build with bash script -

i want create curl #!/bin/sh script , part giving me headache is:

str="-xget -v -h 'authorization: bearer "$token"' https://my_endpoint/sth?" echo $str  con="$(curl $str)" 

the echo there is:

-xget -v -h 'authorization: bearer eyjhbgcioijsuzi1niisinr5cci6ikpxuyj9.eyjlehaioje0ntm5nzixodcsinvzzxjuyw1lijoid2luz3uty2xpzw50lwfkbwluqhnwzwljagvymjewlmnvbsisimlhdci6ije0ntm4odu3odcifq.adlcrv4yph6owwgmlak2rsnc95wk17ulflcisvnwbkea93g4wuq-bmrjnhqeuigsfxsynamgmi36ggc2pytwhkqk8liyrmjth80tggbycnnua2lm26iz2viumk1cj-bh3-dh4hmqsm_hozafnvqgqi9p5j4cbz8ecf_mkc3iq-7enxriktkgakf69-jpffa_9yo26jzzedpymowa-lrpafwptyinzmkauq2shjudwtgmelayzkguooxrz8tgvv9yeb-oneoy54grslb4ogvzawwcj2y6vxmvnpan5wiuzmylqtghnqfr9mop4jid1ravjwt7strp9bchbxd55ctyoeq-ospdv6wkgb07ctcri0spx9ervsab0xf1mh9xkavjoq_dnnpktxlqixmbbosxehjye9k6z30c3uwhcgccndeehxphi7d2bro3m_3fjpksywwk5dxhxmkfpj4flf05jo31ffioj8q7h3c5nevxvk_kes-jpy5ip5xry1dv9p8bwpewfk1-qqrxz1mmnildlxdb9cxe9tm6eo4rxo71h2o4z1dhmnvhhctsatzywsjie3o8ym5o0osms3wh3ej-is572lfv-zqskt3fq927jlvwotd9hhmt2mopf8zg5cdnd-hclzufj7qoi-a0afbn2ct3fccbxj8l4' https://my_endpoint/sth?
